The best things I love while walking in downtown San Francisco are usually odd: Ladies with extraordinarily fancy costume, spray paint artists, a family of confused Asian tourists and most importantly, the street musicians.
What I notice about them is that they never precisely play. However, there is an obvious connection between their emotions and physical movements. Some may call it talent, some may call it trash music, but I call it passion. Music is all about passion, the most important value is your intention of producing music itself. You can play as celestial as you might, if you lack passion, you are no one greater than those street musicians. It never matters whether or not they sound good or educated. As what LV Beethoven said, "To play a wrong note is insignificant, to play without passion is inexcusable".
