Failure provides us with lessons. As long as you’re living consciously and not running on autopilot with zero self awareness, that’s always going to be true. Inactivity, never trying, that doesn’t teach you anything.
You don’t improve, you don’t advance, you don’t develop and you sure as shit don’t win, if you never fucking try.
If the worst that could happen, by trying and failing, is that you learn some tough lessons, you have every reason to go for it.
