Are you different at 38 from who you were at 15?

Honestly, I don't think I've changed that much. At 15 and at 38, I'm still living with some expectation for the person I'll become next. I change today for tomorrow. I change this week for next week. I work this year for next year. I've basically been doing that the whole time. If anything has changed, maybe I've gained a little more patience. Maybe.
