That's a Lot of Kicks

There's a supposed quote from Bruce Lee that I haven't been able to find the reference for. Well, it's a good one, nonetheless: "I fear not the man who has practiced 10,000 kicks once, but I fear the man who has practiced one kick 10,000 times." Here's where I got it. http://www.brainyquote.com/quotes/quotes/b/brucelee413509.html . I like the idea of focus that this quote inspires. And persistence. And the honing of a skill. I consider myself a jack of [many] trades and master of none. Perhaps I should start practicing one kick 10,000 times?
