I have been keeping a journal since middle school. It's a very important part of my life.
Last summer (hot mess, lol!) my journal was, well, extreme. A few days ago I read it and it was actually a very good experience. What seemed so devastating last year is almost comical to me now. It is a good way to gauge your growth (not you per say, just generally speaking).
I am sure a year from now what I am writing will seem ridiculous that I even shed one tear over!
