Hit the wrong note in the recital? Keep playing. The audience barely noticed; they’ll remember that you finished.

Performance errors are far louder to the person making them. From inside, a wrong note sounds like the roof coming off; from the seats it is half a second most people never register. Stopping is what makes it visible, because the stop is the part an audience notices and remembers. Continuing turns a mistake into nothing at all.

Agree with yourself in advance that whatever happens, you play to the end. Practice recovering from a deliberate error so the recovery is trained too. Finishing is the thing people carry out of the room with them.
