Did you ever see that Onion article: "Best years of area man's life apparently never going to happen"
It's a funny article, but it's sad too. This guys spends his entire life waiting for the next big milestone (getting a car, joining the military, getting a girlfriend, etc) and every time he reaches one, his life just changes or gets worse. In the end, he is standing in his garage, and realises that he has nothing left to look forward to.
I'm not going to tell you to "chin-up" or "hang in there baby" because it occured to me a few months ago that the life I'm leading right now at this very moment is probably the best my life is going to get.
