Most of the fun is learning, and it really never stops. A class isn't a bad idea. You might find some 4-hour, 8-hour, weekend classes and stuff like that on Facebook or whatever social networks you use. There are also TONS of great videos available from guys like Jared Polin, Chase Jarvis, Zack Arias, etc. I'm still catching up - there's not enough time in the day to watch it all.
