Andy Roddick, the top-ranked men's tennis player in the U.S. in 2008, wrote about former top-ranked player Andre Agassi:

When I was 17-years-old, we were on a flight together. I was very nervous, but Andre was kind and encouraged me to ask him questions. When I asked about his biggest regret, I expected some answer related to our profession [tennis]. Instead he said it was not starting his charitable foundation earlier.
