"It resists definition yet can be instantly recognized. It comes in many varities, yet follows unchanging laws. It brings rich rewards, yet is not really a goal or a destination but rather a process, a journey. We call this journey mastery, and tend to assume that it requires a special ticket available only to those born with exceptional abilities. But mastery isn't reserved for the supertalented or even for those who are fortunate enough to have gotten an early start. It's available to anyone who is willing to get on the path and stay on it -- regardless of age, sex, or previous experience" -- George Leonard -- Mastery
