It's as you say and that's just life I suppose. If only our younger selves could have seen the big picture, made different choices, maybe we'd be better off later but that's not really how it works I suppose...and life would be different then and now if we manipulated it that way. I'm content with most things I did and accept what happens now, those little things you mention, that mount up. I'm not one to feel regrets much at all and I've had a good life.
News flash: Still having a good life.
