Life is like a staircase. You just got to keep climbing. Otherwise, if you start to overthink it, you'll have trouble taking the next step. There are no branching paths, no point in regretting the actions you didn't take. They say life is a series of choices but that's nonsense cooked up by the old and bitter. Yesterday leads to today and today leads to tomorrow. One step at a time. What lies ahead? You won't know until you get there.
