Open 10 sessions of double or nothing for $1, play extremely passive tight (only playing with exceptional cards). Survive as the good half of winners (normally 10 to a table, so you only need to come 5th), collect winnings and go again.
Extremely boring and ultimately not terribly profitable until higher table levels, when you start playing against people who actually do it for a living. Then it gets harder.
One of my friends does the whole poker for a living thing, he does very well. He's a doctor in maths and physics and has nearly every hand odd ingrained in his brain, and just plays to those odds. I think he makes a couple of grand a month, mainly playing tournaments etc and occasionally getting a big win.
Personally I don't think I could play poker without the constant rush of the gamble/bluff, It'd turn from something fun into a chore.
