About 10 years ago I had dinner with Dr J. One of the people at the table asked him how did he become so great. It was simple he said, 80 percent of the time I was the best player on the court. 10% time I was average and needed to take great shots. The last 10% I was horrible, but the other team did not know it, so I just made myself present.
Sometimes just showing is all you will need is what I heard.
