Men over 30, what is one thing you wish you could tell your younger self?

This is a throwback to an old, similar thread that was locked, but I found it very insightful and there were a lot of interesting comments that were valuable to me as a young woman. I am hoping to get a similar response in this thread.<br><br>So men, what would you say if you could go back to talk to yourself in your teens or early twenties? What are some things you would tell yourself to do? Not to do? It doesn't have to be just about dating/sex, it's about your life. Any advice, stories, experiences, etc you have for your younger self (or any young men reading this thread).
