They said he was too old, but he proved them wrong. Many of my American friends are celebrating the incredible performance of American football quarterback Tom Brady, who just won his 7th Super Bowl. He is 43 years old and the oldest quarterback to ever win a Super Bowl, beating his own record from two years ago, when he was also the oldest quarterback to win it.
He is no longer the strongest or the fastest, but he still has the mentality to win. If he thought he was too old, he wouldn’t have won. But he goes out on the field with a confident expectation that he will do exceptionally well.
You need to meet your life with a similar attitude. There might be others who are stronger or faster, but you have a unique combination of skill, talent, and personality that will make you successful. Work on your self-talk until you believe it.
