Find a team, and work my way up to become a professional player.

I've been playing Dota 2 for a really long time now, I'd say about 9 years now, so I was around 9-10 years old. I've played Warcraft 3: Frozen Throne with different game modes, but mostly with DotA. Then, I heard this Dota 2 thing back in 2011 was coming out or already came out (was still on beta), but I haven't played it until 2013.
