Maturity is becoming someone your future self has fewer messes to clean up after.

Much of maturity is a kind of consideration toward the person you will be in a year. Not leaving them your unpaid debts, unspoken conversations, deferred appointments, and relationships allowed to rot. It is not discipline exactly; it is treating your future self as somebody real.

Name one mess you are currently leaving for later and handle a piece of it this week. The call, the form, the thing you have been avoiding. You will not feel the relief now, and that person will.
