If I knew then what I know now, I don't think I would have had as much fun as I did. There's only once in your life when you can be young and naive and get away with it. It's called freshman and sophomore year.
If I went back having the mindset I have now, I may not have been involved in the situations I got involved in but, at the same time, I wouldn't be the person I am now if it weren't for those experiences. It was those experiences that made me grow up and become the person I am today.
