Everyone else will tell him he did a great job, and he knows it’s true. But their approval means nothing to him because the standards he sets for himself are so much higher than anyone else can possibly set for him. Win or lose, all he thinks about is how he could have done it better or smoother or faster or some way other than how he did it. So the job gets done, but he’s still always thinking about how he could have done more. That’s the relentless pursuit of excellence, always believing in your ability, demanding more of yourself than anyone else could ever ask of you.
