There are many things I could've regretted, but ultimately all of those things made me who I am now. I'm fairly certain I've had more than my fair share of opportunities and made more than my fair share of mistakes, but all I can do is identify them as such, learn as much as I can and try to make myself a better person.
Have a screwed up? Heck yes. Do I regret it? No way.
