Your bank account is a diary of your choices. Read it like one.

A statement records what you actually valued, as opposed to what you say you value. Nobody writes their priorities down honestly, and yet there they are with dates and amounts, including the things you forgot you were paying for. It is an unflattering document and an extremely useful one, because it cannot be argued with.

Open last month and read every line slowly. Put each one in three groups: glad I did, did not notice, would not do again. Cancel one thing from the middle group today, since those are usually subscriptions you stopped using months ago.
