I totally agree with this but also feel it's fruitless to imagine what you'd be like if you knew then the things you know now. Simply put, it's unimportant.

I have no doubt I'd have tried to wear kilts while in high school; but considering the upper-class conservative school district I came from, and the ultra-strict upbringing I labored through, courtesy of my parents, it would have never happened.

This is actually one of the funniest things written in this thread. "Teenaged Me" would have no doubt been scared to death of "Me Now" but we'd both probably be frightened out of our wits by "Middle Aged Me", who's been banging on the door for the past year. I don't think he's going away.
