Don't regret. However, this does not mean YOLO (ech), and go party every night. It means, at least to me, to do those meaningful things you've always wanted, but have been afraid because of how others might judge you.
Always have and always will :) my motto is: "be so good no one can say anything bad; and if they do, be so good that anyone who knows you would never believe it! That is how I have and always will live my life :)
