I didn't really get my shit together until my late 20's, and I kind of stumbled into playing poker as a main income stream.
When I started playing it was because of the competitive aspect and a drive to be the best. I played almost daily for 5 years before I even attempted to try to make a living off it. I was obsessed. I probably spent thousands of hours playing, reading about it, watching videos, browsing forums for information and hand analysis, playing with calculators and solvers.
I've since translated that into a few different income streams to where I can live a modest and humble life without much worry. But I don't need flashy or expensive things to be happy. Just security and freedom.
