Advice to my teenage self

Daily writing prompt

What advice would you give to your teenage self?

You’ll regret more the things you didn’t do than the things you did and went wrong but don’t be hard on yourself anyway
When you’re in your early 20s, you’ll stop going to the gym, stop going to the mountain and stop playing football. Don’t do that, staying active is important. Maybe ditch the football, you’ll need those knees

Good luck!
