Then I got serious about learning , put in another $200, and didn't deposit ever again. Worked that up to around $20kish, kept that as a bankroll, and played in the 5/10-30/60 range, whatever games were good. I mainly focused on limit hold 'em, shorthanded and later heads-up.

I was consistently making in the 150-200 an hour range, but I'm not very money driven and so didn't play that much. Maybe 20-30hrs per week around 6-8 months of the year. So it was easy money and gave me lots of free time, which was great, and the mechanics of the game are truly fascinating and I got very absorbed early on, but you're completely right about how boring and unrewarding it is ultimately.

After a few years I felt like a hamster on a wheel. It became a drag to play so I avoided it and tried to reduce playing to the minimum necessary--which ended up putting strain on the bankroll during bad patches. You're right: the swings are very hard to stomach day in and day out. I didn't save or manage my money at all--spent it mostly on food and travel, which I don't regret. Still, I determined that I absolutely had to do something creative and contributory rather than repetitive and predatory, went the clueless 20 year old failed start up attempt route, learned how to program along the way, and now I'm much happier with life, and though I still make a lot less per hour than those days, it seems conceivable that in a few years I could eclipse it doing something I dig.
