YOLO sucks. It inspires 19-year-olds to make terrible decisions, and it makes the rest of us feel bad when we pass on those once-in-a-lifetime opportunities that seem to come up so often. So I say YOLT. You Only Live Twice! That gives you a lot more breathing room to make mistakes, to go easy on yourself if you fucked it up this time.
Unless this is already your second life, then you're fucked for good.
