"People have always doubted whether I was good enough to play this game at this level. I thought I was, and I thought I could be. What other people thought was really always irrelevant to me"

Steve Nash is expressing his self-confidence in his own capabilities and his neglect for the viewpoints of others. He thinks that he suffices to play the video game at the greatest level and that his own opinion is the just one that matters. He is emphasizing the significance of self-belief and the power of ignoring the doubts of others. He is showing that it is possible to achieve success regardless of the doubts of others. He is likewise demonstrating the significance of believing oneself and the power of believing in one's own abilities. By doing so, he is motivating others to have the exact same confidence in themselves and to neglect the doubts of others.
