Some risks you can’t undo. Those deserve a night’s sleep and an honest second opinion.

Most decisions are reversible, which is why speed usually costs little. A small set are not: a tattoo, a message sent to everyone, money you do not have, something said to somebody you love. For that group the normal rule flips, and the main danger is making the call while you are excited or furious.

Learn to sort them as they arrive by asking what undoing it would take. For anything in the second group, give it one night and one person who will tell you no. If the opportunity genuinely cannot wait a day, that pressure is itself worth being suspicious of.
