Living in the past

Won't do me any good. I was looking at a friends pictures on FB and thinking, if I had stayed in the military, I could be retired. If I hadn't spent 40,000.00 a month, I'd still have plenty of money. If I hadn't worked a hundred hours a week, doing the hardest work imaginable, my back might still have some miles left on it. But then, I think, you know what, none of that happened, or did happen, whichever the case may be, and I just gotta get over it. If I can just learn to get past the past, it might not be too late for me to do at least some of the stuff I shoulda done in this life....
