5 Ways to Develop Mental Toughness and Self-Discipline

June 20, 2018

Mental toughness is one of the most valuable skills a person can develop. Goals rarely unfold exactly as planned. Obstacles appear. Motivation fades. Unexpected setbacks test our patience and resolve. The people who consistently achieve meaningful goals are not necessarily the most talented or intelligent. More often, they are the ones who continue moving forward when circumstances become difficult. The good news is that mental toughness is not something you’re born with. It is a skill that can be developed through daily habits, intentional choices, and consistent practice. By strengthening your ability to manage adversity, make difficult decisions, and follow through on commitments, you can become more resilient in every area of life. Here are five practical ways to build mental toughness and develop greater self-discipline.

1. Pay Attention to Details

Without understanding that which is affecting you, you will be hopeless in mastering adversity.

When you look up to someone who you would describe as mentally tough, what you’re really saying internally is that person is able to endure or recover from difficult experiences or environments.

Without an accurate understanding of what exactly is impacting you, or why you’re feeling or thinking what you are, you will not have the ability to endure or respond appropriately.

If you’ve ever tried waking up earlier, exercising consistently, or breaking a bad habit, you’ve experienced how difficult change can feel. The more aware you become of your thoughts, emotions, and behaviors, the more effectively you can respond rather than react.

2. Make Small Tough Decisions

No professional fighter decides to go big all of a sudden.

They have trained their body and mind over time, beginning with the basics and moving to advanced techniques. Similarly, your mental toughness does not just go big or go home.

Mental toughness is forged in the fires of experience. Each day, small tough decisions must be made. You must make them. Because as you make tough decisions over the small things, you’ll be able to make tough decisions over the big things.

Often times I tell myself “No!” over little things. Things that don’t matter so much. What does matter is my ability to say “No!” over the big things has greatly improved. This is beautifully illustrated in the world of finances.

You want to buy that new pair of shoes but your current pair are fine. “No!”

You feel like buying a tub of ice cream because you’re bored. “No!”

These may seem trivial, but the lesson is huge.

When you train yourself in your decision making for it to not be dependent on external factors, you can consider what is truly best for yourself and others.

As you make tough decisions on little things, you’ll find yourself easily making tough decisions on bigger things.

3. Focus on Solutions, Not Excuses

Blame is an interesting animal. Although I believe credit and consequence are due to the appropriate individuals (which requires the concept of blame), the majority of blame used in the world today has little to do with justice and more to do with excuse.

Do not use blame as an excuse.

Too often we justify our lack of work ethic, lack of progress, failed attempts, or bad experiences on everyone and everything other than ourselves. But guess what? I’m not really interested in you blaming yourself either!

What you must focus on is solutions. The past is only beneficial in so far that you leverage it to impact your future. What has happened, happened. Now, what will you do?

Here are some questions for you to consider next time blame and excuses creep into your mind:

  • What can I do now to heal/grow?
  • What can I learn so this does not happen again?
  • What can I do to achieve a different outcome?
  • Who do I have in my corner, and who can I get in my corner, to help me through this?
  • What attitudes or tendencies do I have that may have lead to this outcome?
  • What skills and abilities can I learn to change my outcome?
  • Are they really that different from me?
  • Am I truly less capable than them?
  • Am I leveraging all that I have available with my skills and abilities?
  • Am I giving all that I can physically, mentally, emotionally, and spiritually?

Mental toughness is a personal act. It’s between you and you. No body else.

4. Honest Self-Assessment Creates Growth

Success is a funny thing because it requires a relatively accurate assessment of your current conditions.

You want to become stronger? Then you must have assessed yourself as weaker.

You want to become wealthy? Then you must have assessed yourself as not-so-wealthy.

You want to publish a book? Then you must be as-yet-unpublished.

To become mentally tough and push through adversity towards a goal, you need to know where you are right now.

If you don’t know where you are, you can’t possibly get to where you’re going. You see this in the exercise industry all the time.

Someone sweats it out in the gym and then stuffs their face with sweets. They have a goal but have no clue where they actually are in that goal progression process.

If they accurately assessed themselves and their condition, paid attention to the details, and began making tough decisions in the little things to strengthen them for tough decisions in the big things, they’d reach their goals more quickly.

Let’s take an author or illustrator for example. Perhaps this is you.

You desire to become represented by an agent or agency and hope to be traditionally published. It’s a worthy goal and I applaud you for taking hold of it! So, where are you?

Be humble.

Are your characters compelling? Does your story create tension? Is your opening strong? Have you sought honest feedback?

Those self-assessing questions help you form an accurate perspective of your own strengths and weaknesses. Now that you know where you are strong and weak, you can develop those skills and abilities. Through acts of humility by assessing yourself and seeking feedback, resource, and knowledge, you can apply tactics and techniques that ultimately bring you a great deal of success.

5. Practice Not Quitting

This may seem a lot easier said than done. And it is. You might find that as you incorporate the first 4 techniques into your life to develop more mental toughness, you’ll find quitting to be one of your weakest areas.

Sometimes changing direction is wise. Persistence does not mean refusing to adapt. It means continuing to move toward meaningful goals despite obstacles, setbacks, and uncertainty.

Mental toughness develops when you continue making progress despite discomfort, setbacks, and uncertainty.

If you want to win at BIG things, BIG goals, BIG successes, you must stoke the fire of success in the little things.

For 1 week (that’s only 7 little days), set a goal of waking up at a specific time each day. exercising for a certain amount of time or 5 of those days, and reading something for a certain amount of time for 6 of those days. If you DO IT, after 1 week you will achieve an incredible level of personal success.

What do you think you do next? You increase the stakes. Increase the goal. Increase the challenge.

Mental Toughness Is a Skill, Not a Trait

Many people assume mentally tough individuals were simply born that way.

In reality, mental toughness is developed through repeated exposure to challenges.

Every difficult conversation, disciplined choice, setback, and obstacle becomes an opportunity to strengthen resilience. Like physical fitness, mental toughness grows through consistent practice.

Mental toughness is rarely built during life’s biggest challenges. More often, it’s built during ordinary days through ordinary decisions.

Pay attention to the details.

Make small difficult choices.

Focus on solutions.

Be honest about where you are.

Follow through on your commitments.

Over time, those small actions compound into something powerful: the confidence that you can handle whatever comes next.
