how to become great

...Ericsson's primary finding is that rather than mere experience or even raw talent, it is dedicated, slogging, generally solitary exertion — repeatedly practicing the most difficult physical tasks for an athlete, repeatedly performing new and highly intricate computations for a mathematician — that leads to first-rate performance. And it should never get easier; if it does, you are coasting, not improving. Ericsson calls this exertion "deliberate practice," by which he means the kind of practice we hate, the kind that leads to failure and hair-pulling and fist-pounding.
