Turning Thirty

Its odd that as I grow older I understand more things but that understanding doesn't bring any clarity.  I understand now why people stay in relationships and put up with things that they typically would never put up with when they were 17 or 18.  I also understand why people feel the pressure to do things, whether it be kids, getting married, changing careers, changing their appearance and any other thing that I used to look at with a slight disdain.  But at the same time none of that offers me any clarity on my own situation.  I know I should be thinking about settling down with a girl and contemplating a family because thirty can quickly turn into thirty-five and then forty and at that point it might be too late.  But while I think about, and I guess to a certain extent that creates some internal pressure, the reality is that I really do nothing about it.  I am content with what I have and I feel like things should happen organically.  I don't want one of these contrived life situations that that are merely products of the external pressures of family and friends.
