Sometimes the cost of a decision arrives long after the excitement has left.

The bill for a decision frequently arrives long after the enthusiasm has gone, which is why the enthusiasm is such a poor guide. Whatever made it exciting will not be present when the consequences show up, and you will be handling them in a much more ordinary state.

Evaluate a decision in a flat mood rather than a high one. Ask whether the plain version of you would still choose it. That version is the one who will be living with it.
