The home run theory of careers:
What matters is eventually hitting a home run, and the way to do that is training hard and a lot of at-bats. You only have to be right once, and it's ok to be wrong a lot of times.
Be bold. Move fast. Work hard. Ignore haters. Keep swinging.
Love this speech by Bill Gurley - one of the common things across top professionals like Bob Dylan, Danny Meyer, etc was that they studied everything they could find about their field, they were masterful students first.
