Garry Kasparov's presentation "Achieving Your Potential" is filled with insightful advice about how to maximize one's chances to be successful:
Kasparov achieved the highest rating in chess history--a record since broken by Magnus Carlsen--and he held the Classical World Champion title from 1985 until 2000, withstanding challenges from Anatoly Karpov, Nigel Short and Viswanathan Anand (who became the World Champion in 2007 and has held the title since that time). Kasparov seemed to be at the peak of his powers on the eve of his 2000 World Championship match against Vladimir Kramnik, who he had taught at the famous Botvinnik Chess School. However, Kasparov had become overconfident and Kramnik had detected some weaknesses in Kasparov's game. Kramnik surprised the chess world by defeating Kasparov and ending Kasparov's reign.
Starting around the 21:25 mark of the video, Kasparov explains what went wrong: even though he was still working hard on his game, at some level he had internalized the idea that he was unbeatable--but Kramnik came up with new ideas and repeatedly steered the games onto uncomfortable terrain for Kasparov. Kasparov viewed this failure as a learning experience, he went back to the drawing board and he maintained his status as the highest rated player in the world until he retired from professional chess five years later. Along the way, Kasparov played 11 serious games against Kramnik, scoring one win and 10 draws. Kasparov says, "That's good enough. That's a big change" compared to the result of the 2000 match.
Kasparov declares, "We should not be too proud to learn from the young generation. Otherwise, we'll not able to come back."
