Failing where people can see is expensive for your ego and cheap for your growth.

Public mistakes hurt more than private ones and teach faster, because you cannot quietly pretend they did not happen. The embarrassment passes far sooner than you expect, since other people are mostly thinking about themselves. What remains is a correction you are unlikely to need twice.

When something goes wrong in front of people, say plainly what happened rather than managing the story. Fix the thing visibly and move on without a long apology. Being willing to be seen getting it wrong is what lets you learn at full speed.
