Lasting friendships are surprisingly rare. While most people have dozens of acquaintances throughout life, very few enjoy friendships that continue growing for decades. The good news is that lifelong friendships aren’t accidental—they’re built intentionally. One of my closest friendships has lasted for more than 30 years. As I reflected on why that relationship endured while so many others gradually faded, I identified seven principles that consistently strengthen friendships over time.

Why Lasting Friendships Are So Rare

Most friendships don’t end because of one dramatic disagreement.

They slowly fade.

Life changes.

People move.

Careers become demanding.

Families grow.

Schedules become crowded.

Without intentional effort, even meaningful friendships naturally drift apart.

That doesn’t mean the friendship wasn’t genuine.

It simply means relationships, like gardens, require ongoing care.

The seven principles below have helped one of my closest friendships thrive for more than three decades, and I believe they can strengthen yours as well.

7 Keys to Building Lasting Friendships

Adopting these elements of lasting friendship will not only help you improve the quality of your friendships, you may happen to cultivate a real best friend in the process; a best friend that stands the test of time.

1. Value the Person over Preferences

Any deep, meaningful friendship will be filled with similarities AND differences.

If you don’t have any differences yet, you probably don’t have a deep and meaningful friendship!

Without a doubt, there will come a point where we must decide if we value the person more than we value our position.

When their opinions differ from our own, what will we do? Keep forging the friendship or back away and let it die?

I’ve found this to be true in my life. One of my absolute best friends and I have many differences. We do NOT see eye-to-eye on everything.

We don’t always agree religiously, politically, or on a number of less polarizing topics like food or health preferences.

We debate. We discuss our differing views. But we never place our position over the other person.

Who someone is is far more than what they might think or do. They are human, created in God’s image, as Genesis 1:27 records.

Even deeply held convictions can change over time. Who knows, after 20 years your best friend might just start seeing things the way you do. Wouldn’t that be fun!

2. Let Yourself be Inconvenienced

If you’re like me, time is precious.

Our lives are becoming busier every day and if we’re not careful, we can overbook ourselves right out of friendships.

As kids, we often find time with our friends is very easy and natural.

We saw them at school, in the neighborhood, on the bus, at events our parents dragged us to, online, and over the phone.

Hanging out was soo easy!

And then responsibility came with a vengeance.

We went to school and had to focus on our studies.

We got a job and needed to concentrate on our deadlines.

We started a family and found their needs (and wishes) trumped every external priority imaginable.

Quick as lightning our hours of hangout with friends time turned into a chore. It became just another thing to get done somehow someway.

And seeing it like that is exhausting!

Unfortunately, there’s no easy way to say this. Cultivating friendships are not always convenient.

In fact, researcher Jeffrey Hall from the University of Kansas noted friends need to spend at least 300 hours together to become true best friends!

Recently, a great friend of mine, one that I’ve known since Kindergarten (I’m decades past that if you didn’t know…) flew into the same state as me.

They were here for business but there was a sliver of a chance they would be within two hours drive of where I live.

The chips were stacked against our friendship right away.

Their schedule was unpredictable. It was during a work day. And my family calendar was booked up.

What would you do?

Hopefully it’s what I did.

Carve out the precious time and start driving.

It was a special, worthwhile time of reconnection for me and I trust it would be in your situation too.

3. Don’t Settle for What Used to Be

People change.

Simple as that.

As children or young adults, we can think back to the simplicity of our friendships.

If we’re not careful though, we can spend all our time wishing the friendship of today is the same as it was back then.

We aren’t back then though and the person we remember has changed.

We’ve changed too.

Along the way, they and us have picked up some bad habits. Or some odd views. Or even chosen a lifestyle that is very different than us.

Refer back to point number 1.

What’s more important…how they/we have changed…or who they/we are?

Exactly. While it’s a lot of fun to reminisce and chat about the old days, the here and now matters most.

The activities we used to do with our friends don’t always work in our current schedules.

As active, hard working adults, we don’t have hours to chat on the phone.

Or the latest video game console to go on epic quests together.

We can’t just walk across the street and see what their parents are making for dinner.

Or throw rocks at their window so they know we’re outside.

Life gets complicated.

But the new normal must be sought out after.

The new connection with our friends might be a scheduled walk in the neighborhood, a hike near by, lunch out during the week, a brief call on our way home from work, a movie, or a long drive (or long flight) to spend a few hours (or days) together.

4. Seek the Best in and for Others

Nothing wrecks genuine friendships like jealousy or bitterness.

As we age, life choices magnify our differences with friends.

If our friend has wonderful children and we are struggling with fertility…

If our friend is skyrocketing financially and we are barely making ends meet…

If our friend lands the job we wanted…buys the car we dream of…goes on the vacation we had in mind…

What do we do with those feelings?

They must be processed for what they are. Simply differences between one life and the next.

Our journey isn’t their journey and vice versa.

A friend…a real true friend…wants the best for you.

And if you’re a good friend, you’ll want the best for them.

I have personally found over the years that celebrating the wins in the lives of others is fun and freeing.

If this is a struggle, consider digging into what is holding you back.

The answer might just be thanking God for all the goodness he has poured out on your friend and yourself in different ways.

Then, be sure to let them know how proud of them you are for whatever is going well in their life.

5. Sharing is Caring

It’s very natural to want good things all to ourselves.

With friendship however, people are not meant to be trapped.

Becoming a great friend includes supporting other friendships that form, whether they are generated by your own influence of external situations.

This perspective comes from plenty instead of lack.

Hoarding is an unfortunate human tendency but it stifles and limits the potential not just of our friendship but of the success, satisfaction, and fulfillment of our friend.

Now, don’t get it twisted. Sharing our friend with others and promoting those friendships may draw that friend away.

We may get less time with them or lose them entirely in our go, go, go busy world.

But simply put, that’s life.

Losing a friend’s time or attention because they prefer to focus on someone else has to be OK.

No one wants a friend that is trapped.

Ultimately though, supporting our friends by promoting their own growth and connectedness with others is a good thing that should deepen our friendship with them.

Worst case scenario, if they choose to gravitate away, it’s a sign for us to stay open to new friends that may have a very real need for us in their life right now.

It’s very possible that the season of distractedness will be short lived and the excitement of a new friend fades away, causing them to return to people they know support and cherish them as a person.

6. Vulnerability Nourishes Friendship

Without the right ingredients, a healthy plant will shrivel up and die.

Have you ever brought home a beautiful potted flower from the store?

You think you have the perfect spot for it at home, either outside in a garden or inside by a nice window.

You water it often.

You trim or weed it regularly.

Days turn to weeks, weeks to months, and before you know it a year has gone by.

The flower, once remarkable and noteworthy, looks frail and dry.

The flower hasn’t bloomed in some time and the once green leaves are now a mixed shade of disease.

What happened?

You cared about it.

You loved it.

You really did.

But somewhere along the way, the vital needs of the flower were unattended.

It could have been not enough water on an unreasonably warm day.

Or maybe a a bug crept in and nibbled at its vulnerable roots.

Perhaps the soil wasn’t balanced with proper nutrients.

Or it was the Sun. Too much direct light.

Maybe not enough.

Regardless, the beauty of the flower faded.

Just like our friendships can fade.

It may not be any one thing that causes friendships to falter, but falter they often do.

And once the friendship looks more like a bouquet of dry flowers than a symbol of undying appreciation, it’s difficult to recover.

All the more reason for us to consistently nourish our friendships with one of the best ingredients: Vulnerability.

To be vulnerable is to be open. Transparent. Free.

Sharing who we are, what we really think, and what we really want takes courage.

Personal development author Shane Parrish believes hiding struggles is weakness rather than strength!

It takes humility.

Being vulnerable with our friends also helps our friends to be vulnerable with us.

Vulnerability takes one intentional initiative. It will not happen on its own.

Either they take the step.

Or we take the step.

Since all we can control is ourselves, how about we take the step?

Then, watch what happens and reap the rewards of a deeper friendship.

7. Keep Growing as a Friend to Others

Many things in life happen on their own.

Our heart pumps.

Our lungs expand and contract.

Our body grows.

We learn many things in formal education and even more on the road of life.

Being a great friend isn’t a one-and-done act. It takes a commitment to learn from others.

It takes trial and error.

It takes adapting to others as we learn more about them and ourselves.

I have a friend who is very careful about what they say. I know they are slow to speak in a good way. When our friendship was young, I often talked over them a little bit or didn’t wait long enough before transitioning from one topic to the next.

As I learned more about them, I realized I could adapt my communication style to help both of us. Now, I try to be more comfortable in a delayed silence. It isn’t always easy, but it is always worth it.

Another friend of mine is a chatter box, in a good way! They have so much to share and thoughts on everything. As a friend, I really want to know what they’re thinking. But it requires me to be intentional about interjecting to share my own thoughts, or being more focused on letting them get their ideas out up front because then they are more able to listen to others.

No doubt you’re thinking of all your different friendships and the ways they express themselves.

Keep learning how to be a better friend. I think you’ll find your friends will be learning too.

Frequently Asked Questions

What makes a friendship last?

Lasting friendships are built on trust, respect, vulnerability, shared experiences, and a willingness to invest in one another over time. While every friendship is different, choosing the person over temporary disagreements and continuing to grow together are two of the strongest predictors of a friendship that stands the test of time.

How long does it take to build a close friendship?

Research suggests that meaningful friendships develop gradually through consistent time together. One widely cited study from the University of Kansas found it can take roughly 200 hours to develop a close friendship and 300 hours or more to become best friends. Deep relationships aren’t built overnight—they’re cultivated through repeated conversations, shared experiences, and mutual trust.

Can friendships last a lifetime?

Yes. Lifelong friendships are uncommon, but they are absolutely possible. The strongest friendships continue adapting as life changes through careers, marriage, children, moves, and new responsibilities. Lasting friendships require intentional effort rather than assuming the relationship will maintain itself.

Why do friendships fade?

Most friendships don’t end because of one major disagreement. They slowly fade as schedules become busier, priorities shift, communication decreases, and intentional time together becomes less frequent. Maintaining a friendship requires continued investment from both people.

How do adults maintain friendships?

Adult friendships often require more intentional planning than childhood friendships. Scheduling lunches, making phone calls, sending encouraging messages, celebrating important milestones, and creating regular opportunities to reconnect all help friendships remain strong despite busy lives.

What are the qualities of a good friend?

A good friend is trustworthy, encouraging, honest, loyal, forgiving, and willing to listen. Great friendships are built on mutual respect, genuine care for one another, and a desire to help each other grow rather than compete or keep score.

How do you rebuild a friendship?

Rebuilding a friendship usually begins with one person taking the initiative. Reach out, acknowledge the distance if appropriate, and invite the other person to reconnect. While not every friendship can be restored, humility, forgiveness, honest conversation, and consistent effort often create opportunities for healing.

Why is vulnerability important in friendship?

Vulnerability allows friendships to move beyond surface-level conversations. When people honestly share their struggles, fears, hopes, and successes, trust deepens and emotional connection grows. Healthy vulnerability also encourages the other person to open up, creating stronger and more meaningful relationships.

Final Thoughts

Deep friendships don’t happen by accident.

They’re built through thousands of ordinary decisions made over many years.

Choosing people over preferences.

Making time when life is busy.

Being vulnerable.

Celebrating one another’s successes.

Continuing to grow as a friend yourself.

You don’t need dozens of lifelong friends.

Even one friendship that continues growing decade after decade is an incredible gift worth investing in.
