One good motivational quote for athletes is from baseball legend Babe Ruth: "Never let the fear of striking out get in your way.” Experts say motivational quotes can inspire athletes and actually improve performance on the playing field.
The Center for Sport Psychology and Performance Excellence at The University of North Texas compiled a good a list of motivational quotes on their website, broken down into ten categories.
Among them is this good quote about motivation from boxer Muhammed Ali: “Champions aren't made in the gyms. Champions are made from something they have deep inside them -- a desire, a dream, a vision.”
Former Pittsburgh Pirates pitcher Vernon Law had this to say about overcoming adversity: "Experience is a hard teacher because she gives the test first, the lesson afterward."
College basketball coach Bobby Knight emphasizes that the real opponent in any sport is the game itself: "You don't play against opponents, you play against the game of basketball."
NFL coach Chuck Noll has a good variation on the famous quote from sportswriter Grantland Rice, "It's not whether you win or lose, it's how you play the game." Noll extends the advice to coaches: "A life of frustration is inevitable for any coach whose main enjoyment is winning."
