Quincy Jones is one of my music heroes. He has 80 grammy nominations, 28 grammy's, 41 albums, and 14 soundtracks over a 60 year career. Quincy addresses success by saying "Good luck usually follows the collision of opportunity and preparation". He also believes your insight is guided by your experience. "If you don’t have the science together (practice), your soul (passion) just doesn’t have a clue how to get where it wants to go!" It takes 10,000 hours of study or practice to make those instinctive determinations.
