I know what your feeling Stabber. I just turned 23 a few weeks ago and found myself thinking the same things. But at the same time I realized, with the help of some people on WBB, that 23 isn't very old. You've got tons of time to figure yourself out. Take it from me, I was married at 20 and divorced at 22. When I was married I began to feel that I was missing out on just being single and not having the stress and worries of a married person trying to support a family. I'm not saying I'm glad my wife turned out to be a dirty slut, but.... Let's just say I've been on both sides of the coin already and I know what it's like being where you say you wish you were. Enjoy the time you have. Life is what you make of it. Personally, I'm tired of wasting mine worrying about tomorrow. You should consider the doing the same.
Hope things look up bro!
