Robert Greene wrote a book called Mastery, which Jeff Bezos referenced once at a conference, describing mastery as something taking approximately 10,000 hours of hands-on doing to achieve. I started playing CS in 1999 when it was a Half-Life mod. I think it's possible I've reached 10,000 now, at least including other team-based FPS. Do I play with mastery? Steam supports Assyrian cuneiform characters, CS:GO does not, which is why my name appears blank in that game.

I can't play CS:GO seriously anymore. The matchmaking ruins it.
