The typical answers are: education, military, sports, entertainment. You either need to work hard in education or go join the military and survive or be naturally gifted in sports/music.
Almost all of the people I have seen called 'gifted' in music are ordinary people that were given the chance to develop in music, both through their parents, and through things like council-funded music/orchestral programs, etc.
All the people I know who have been successful in music worked their asses off at it. It takes a special kind of personality to practice by yourself for hours and hours in search for perfection while still having he ability to connect with other people emotionally.
