Make reversible decisions faster and irreversible decisions clearer.

Not all decisions deserve the same care, and treating them equally is how people end up agonizing over lunch and rushing a marriage. When a choice can be undone cheaply, speed costs almost nothing and teaches you something. When it cannot be undone, the value is in clarity about what you are actually trading away.

Before deliberating, ask what it would cost to reverse this if you were wrong. If the answer is small, decide now and learn from the result. If the answer is large, slow down and get specific about the assumptions the choice depends on, then decide anyway.
