Break Free from Decision Fatigue: How 100% Commitment Clears Your Mind


They say it’s easier to have 100% commitment than 80% or 90% to your goals. I’ve definitely found this to be true for myself. When we’re only committed 80%, we give ourselves wiggle room, and this is where we start to make decisions and negotiations with ourselves.

The Downside of Partial Commitment

Let’s take the example of deciding to give up sugar. If you’re 80% committed, you might think, “I’ll just have it on this occasion,” or “Maybe on that occasion,” or “Perhaps on this other occasion.” This leads to a slippery slope of constant negotiation.

When you leave room for negotiation, your brain starts to argue for why certain situations should be exceptions. This back-and-forth can be exhausting and often leads to breaking your commitment.

The Strength of 100% Commitment

However, if you commit 100% – deciding that there will be no exceptions – there’s no wiggle room. Your brain doesn’t have the opportunity to start negotiating because the decision is absolute.

Benefits of Full Commitment

1. Clarity: A 100% commitment leaves no room for doubt or debate. You know exactly what your boundaries are.
2. Mental Freedom: Without the constant back-and-forth of negotiating with yourself, you free up mental energy for other tasks and decisions.
3. Consistency: Full commitment leads to consistent behaviour, which is crucial for building and maintaining new habits.
4. Self-Trust: By sticking to your commitments, you build trust in yourself. You become someone who follows through on their promises, both to yourself and others.

Practical Steps to Achieve 100% Commitment

1. Make a Clear Decision: Define your commitment clearly.
2. Anticipate Challenges: Recognize situations where you might be tempted to break your commitment. Plan how you will handle these situations in advance.
3. Create Accountability: Share your commitment with someone who can support you and hold you accountable.
4. Track Your Progress: Keep a journal or use an app to track your daily adherence to your commitment. Seeing your progress can be motivating.
5. Reward Yourself: Set up small rewards for sticking to your commitment. Celebrate your successes to reinforce your new habit.


  • Clear Decision: ‘I will not consume any sugar for the next 30 days.’
  • Anticipate Challenges: Prepare for social gatherings by bringing your own snacks or eating beforehand.
  • Create Accountability: Tell a friend or family member about your commitment and ask them to check in with you.
  • Track Your Progress: Use a habit tracker app to log each day you stick to your commitment.

  • Anticipate Challenges: Set a specific time each day dedicated to writing and eliminate distractions.
  • Create Accountability: Join a writing group or find a writing buddy to share your progress with.

  • Anticipate Challenges: Create a content plan and write drafts in advance to ensure you always have material ready.

  • Hmm. That really makes sense, and it makes me realize that there are a lot of times that I don’t make a 100% commitment. I guess I really like wiggle room. But as you said, it leads to decision fatigue. I’m going to think on this and see if I can help myself be more committed.

  • Staying committed to my health goals has generally been tricky for me. I have to give myself grace as there are habits that need to be unlearned and healthy choices that need to be reinforced. To be 100% committed to myself, that is what I’d like to be.

  • That is so true. I used to tell this to my son when he was younger. He made the hockey team and had his set practice schedule, which would of course collide with say, birthday parties, play dates and the like. I said “look, if everytime something fun comes along, you cancel practice, there will be a reason for exceptions every single week. That way you won’t make it to the lineup.”
    Sugar is a great example. Even though you’re 100% committed though, you will always run into hidden sugars in breads, sauces and the like.
