We live in an era of infinite choice. Unlimited information, endless entertainment, and a thousand different ways to “optimize” our lives.

But for the human brain, infinite choice is a trap. It leads to Decision Fatigue—the deteriorating quality of decisions made by an individual after a long session of decision-making.

When you have too many choices, you often choose nothing. This is why “positive constraints” are your best friend in the journey to becoming someone new.

The Freedom of the Fence

Imagine a playground on a busy street. If there’s no fence, the children stay huddled in the center, afraid to wander too close to the traffic. If you put up a fence, the children use the entire space. They are free to play because they know where the limits are.

Positive constraints are the fence for your habits.

By pre-deciding your actions and limiting your options, you free up mental energy for the actual doing.

The Three Types of Positive Constraints

1. Environmental Constraints

Make the “wrong” choice physically difficult or impossible.

  • Example: Want to stop scrolling? Leave your phone in another room at 9 PM.
  • Example: Want to eat healthier? Don’t buy processed snacks. If they aren’t in the house, you don’t have to “decide” not to eat them.

2. Temporal Constraints (Time-Boxing)

Give your habits a specific, non-negotiable time slot.

  • Example: “I meditate at 7:15 AM,” not “I’ll meditate sometime this morning.”
  • How Becoming helps: By assigning your habits to specific times or rituals, you eliminate the “When should I do this?” decision.

3. Procedural Constraints (The “Only One” Rule)

Limit the variety of your habits to reduce complexity.

  • Example: Eat the same breakfast every weekday.
  • Example: Wear a “uniform” to eliminate the morning “What should I wear?” fatigue.

Designing for Success in Becoming

Becoming is a system of positive constraints. It doesn’t ask you what you want to do today. It asks you to perform the habits you’ve already committed to.

  • Pre-selection: Spend 10 minutes on Sunday setting up your week. Choose your identity and your habits.
  • Zero-choice execution: On Monday morning, you don’t decide. You look at the app and see what’s next. The decision was already made by “Sunday You,” who was rested and strategic. “Monday You” just needs to execute.

Constraints Create Creativity

It sounds counterintuitive, but limitations breed innovation. When you tell yourself, “I must write for 10 minutes every day,” you stop waiting for inspiration and start looking for small things to write about.

Constraints take “No” off the table. They make the habit the path of least resistance.


TIP

The Power of the Default Set your digital and physical environments to “Good Habit” as the default. Make Becoming your home screen. Put your book on your pillow. Lay out your gym clothes. When the default is the habit, you save your willpower for the rest of your life.
