You should be confident in what you do, but know that failure can still happen — and failure is not good. That’s how you avoid failure itself — by seeing it as possible, and correcting mistakes which can lead to failure along the way, not the next time around.
What’s not ok is assuming that if you fail, everything is ok and you still get a trophy — sorry, you failed. Some of your employees lost their homes, cars, and have suffered because you failed. So no, you don’t get a trophy, or a feather in your cap, you’re just an ass going around a telling people that you are only more awesome now because you failed.
