This is a great short video showing Olympia LePoint talking about how she overcomes fear. Olympia was a NASA rocket scientist and had to overcome much in her life to get there. She was bought up in poverty in LA, with a crack house next door, and failed most of the math courses when at school.
But by facing her fear, naming it, giving her brain a different focus and thereby rebuilding the neurons in her brain she won out. She became one of the highest finishing maths graduates.
