Casey Neistat is definitely one of my heros, i recommend you check out his youtube channel subscribe and watch his keynote presentation where tells you about his life. it is one of the most inspiring stories for one reason alone. that reason is he literally never knew what he was doing. no matter if he was signing a contract to work with nike or any other project that he took on. he did it because he had a gut feeling about it and never let fear stop him! and that is one of the main keys to success!
