I'm not talking completely, but to be able to take all the knowledge that you've accumulated over the years and go back to, say 16 or 18 and do things differently? Right now I just wish I could start over. Go back to 18 and make better decisions in regards to my life and things that have since affected my future. Granted, there's some things I wouldn't want to change (like having my daughter) but so much more I wish had never happened, or that I had not chosen to do. I'm not alone in that, am I?
