Control+Z Effect

On a computer, every mistake has an antidote: undo. Watch what that does to behaviour — people experiment freely, because the cost of error is one keystroke. Remove the undo, and the same person becomes timid, slow, careful to the point of paralysis.

The principle reaches far beyond software: willingness to try is proportional to the cost of failing. Cheap reversals make explorers; expensive ones make bureaucrats.

This is a design lesson for your own life. Most decisions are far more reversible than they feel — the course dropped, the room repainted, the apology offered, the project restarted. We treat them as carved in stone, and so we never carve anything.

Before agonizing over a choice, ask one question: can I undo this? If yes, decide quickly and learn from the result. Save the long deliberation for the few truly permanent moves. Most of life is editable — live it in draft.
