I've just finished reading an excellent book "What Drives Winning" by Brett Ledbetter. He gives a ton of examples of outstanding athletes and the work they put into being great. One story from the book that we shared with our team is:
Here’s something that Kevin (Durant) told me he started doing as a freshman when he played basketball at the University of Texas: "One thing I try not to do is be a guy that goes into the gym and wants to be the only guy in the gym. I don’t want to be the guy that says 'I was working today, what were you doing?' I want to pull my teammates into the gym with me. If I work hard and we all work hard, I know only good things can come out of it."
