Not all basketball talents play at the NBA. And there are musicians after Mozart and the Beatles. Look at people you can admire, and make even tiny steps by their standards. You can be 10% Bill Gates (example, pick your own), or 1%, or 0.01% or 0.0001%. But you are both on the same track. The important thing is to push your limits to something you believe is worthy and that you can give a unique contribution that pushes that something an inch forward. Good luck.
