Yes and no. Have you ever gone back and read your old journal entries? It can be a very eye-opening experience. I used to do it regularly and decided it was futile. I learned my lesson.
It’s fun to see what I was thinking all those year ago, but eventually I realize that the voice and the thoughts haven’t changed much. I struggle with the same issues, exalt in the same joys and response in mostly the same ways. Mostly. Maturity does come slowly.
