How do I practice version control ideas?

The most direct way to practice version control ideas is through a focused exercise: Find a belief you have held for at least three years — about management, about a technology choice, about how relationships work. Write down what you believed three years ago as Version 1. Write your current position as Version 2. Then write one sentence describing what evidence or experience caused the shift. You now have a versioned atom with a changelog. Store all three together.

Common pitfall: Overwriting old notes instead of appending new versions. When you delete your previous position and replace it with your current one, you destroy the evidence of your own intellectual growth. You also lose the ability to notice patterns in how you change your mind — which directions you tend to revise, which beliefs resist revision, and which topics you cycle on without progressing.

This practice connects to Phase 2 (Atomicity and Decomposition) — building it as a repeatable habit compounds over time.
