I've been playing 3/5 NLH 500 cap for the last year or so after making the conversion from limit holdem. I've been tracking my stats since Jan 2014 and right now, after 472 hours, I'm up 12.5K which is 26.5/hr winrate (btw, using a phone app like poker history plus is much, much easier than doing it all on paper and pencil or via excel). Nothing stellar but I'm still working on fixing some leaks in my game like decreasing my hero calls and working on maximizing by value hands a bit more. My goal is to maintain or improve my results thus far for the next 6 months and look into quitting my $20/hr job and do poker full time. Poker is really all I think about when I'm working and it's what I love to do when I'm off work. In fact, the last "vacation" i took for 2.5 weeks I spent 70 hours of it playing poker and made 5.5K which is a couple months of standard work pay. I don't have anyone depending on me for income other than myself so I think I'm in an ideal spot to do it. Plus, the casino i'm at is large enough and has enough reg games that I'm not worried about the action dying out or anything as there is typically 3 tables and weeknights and 6+ games of 3/5 on weekends.
I'm working on my bankroll right now. Currently, I have 10K cash for living expenses and another 15k cash for poker plus 30K in investments (401K, ira, etc). If I can get up to 25K in poker funds by 2015 I feel I would be very comfortable to play poker and use that as income. I also feel that playing consistently would help my own game to grow and improve as I would be able to put in around 40 hours/week as opposed to the 20ish hrs/week that I do now. Also, I hate having to play after work as I'm more tired and not at my best or can't play for long because my game really suffers when I get tired.
So, that's where I'm at and where I'd like to be. We'll see how it goes. So far, July is off to a good start at 3K profit after 65hrs play.
