John Force is an NHRA drag driver. He has over 144 victories and is a major player in his field.
As a child, he overcame childhood polio. As a young adult, he raced for twenty years and failed so miserably that he became the butt of jokes.
But he never gave up.
Most of us attempt something a few times and throw in the towel after a few failures.
What are you passionate about? Can you endure hundreds of fails? Public mockery? If you enjoy the process, (the learning and growth) instead of focusing on the end game, it takes care of itself.
