Yes, I think about it.. But then I also think that it's not any worse that watching tv.. And then I also look at those thing that I have "achieved" in my life: I got a lovely girlfriend.. I got the best family.. I got great grades.. And I'm on a contract with my soccer club.. :-$ So, yes I think about it. But when I look at it in a perspective with the other things I can't really bother worrying.. :)
