At the risk of getting BBQ-ed, knowing how to handle a mistake or clam is also very important. This past Chirstmas I attended the Airmen of Note concert. It was a fabulous performance. I don't even remember the name of first piece, but it started with some high work by the lead guy -very exposed. There were a couple of craked notes. Instead of the other guys turning and looking at him, they remained forcused, eyes front as if nothing had happened. The lead guy also acted as if nothing had happened. (by the way-lead player was excellent and "right on" for the rest of the concert). Perhaps the best example to learn from is Maynard. (No BBQ, please). While an excellent player until his death, it was obvious that his skills were not as strong at the end of his life as they were in the 40-80s. Having attended his concert whenever possible from when he came to the states from England, there were nights when he played very well and others when the "key" notes just didn't come. He always handled it with a smile. We can all learn a lot from him.
