How to write personal principles you actually use

A personal principle is a reusable decision rule. It is specific enough to guide behavior, flexible enough to survive real life, and personal enough that you remember it when it matters.

Start with a real moment

Good principles usually come from friction: a decision you keep revisiting, a pattern you dislike, or a lesson you paid for with time and energy.

Instead of starting with a broad value like “discipline,” start with a sentence from your life: “I lose the morning when I check messages before deep work.”

Turn the moment into a rule

Rewrite the observation as a default action. The best version is short, active, and connected to a trigger.

Example: “Messages wait until the first deep-work block is complete.” That principle has a trigger, a behavior, and a reason you can remember.

Add one exception

Rigid rules break quickly. Add an exception so your principle can handle reality without becoming vague.

Example: “Messages wait until the first deep-work block is complete, unless a client launch is live today.”

Principium workflow

  1. 01 Capture the raw observation as a principle draft.
  2. 02 Group it under Focus, Work, Health, or Relationships.
  3. 03 Attach a visual anchor that reminds you of the situation.
  4. 04 Review the principle before the next matching moment.

Concrete examples

  • Raw: “I say yes too quickly.” Principle: “Pause before accepting work that changes the week.”
  • Raw: “I avoid hard conversations.” Principle: “Name the tension while it is still small.”
  • Raw: “I over-plan instead of starting.” Principle: “Make the next action visible before improving the system.”

Turn the idea into a principle

Principium gives your best reflections a place to become standards, reminders, and decision rules.
