Congrats!
If I ever think of all the things I didn't do in my life (because I am scared or for whatever reason), I start thinking YOLO (but in a positive and not slutty way haha). It might help you to be working on the better you while not feeling old haha. (I see you like to reflect ) so do what you want or feel like, as long as you make a note to yourself that you are absoluetly sure you want to do it. That way you (hopefully) wont regret things in your life :) It helps me do what I want haha without regetting it.
