I'm interested in what exactly it takes to "go pro"

I'm not an amazingly good poker player or anything like that, but i'm intrigued by the people here who seem to make money from it.

i mean, if you wanted to make a decent wage, how often would you have to play, at what limits, etc etc. I understand there is a fair amount of variance out there etc etc...but are there some people here just happy to pay the bills and put away a bit of savings?

so, if you don't mind...what's your story pro's?
