Like what? Define amazing. Become the founder of some extractive start up? Write some bs science and gain a nobel prize? Be the best chess player?
My view is that you always have to put yourself together. Intellect is simply a factor, but so is honesty and the state of your heart. You can be very smart and you can still be stupid. You sound a bit resentful, but do you ever consider that your experience grants you the opportunity to lead life away from the well-travelled track to success, and do something personally and actually meaningful?
