Recreational players tend to not track results so I doubt some of the responses can be taking all that seriously.

In terms of the question of low stake pros I view it as possible but as everyone else has said it depends on how a person wants to live. The person would need to seriously track their results though before attempting it. The biggest mistake would be assuming you can make 50k a year off 3-4 hours a week of play. It takes alot of serious self motivation to play this as it requires the time to be put in every week just like any other job you have to show up to work. It all depends on living expenses the person needs just as others have said. Most difficult thing for a small stakes pro is not dipping into their bankroll for expenses. Always pay yourself an hourly wage than rest goes to your bankroll to allow yourself to move up.
Personally I think the best thing a low stakes player could do is have a part time job of any kind (maybe even dealing) and play part time. It gives you at least some sort of steady income and some part time jobs offer insurance which could help alot too. It helps if you have another working spouse as well so that you can be covered under their insurance. Different ways of going about it for different people but lots of ways to make it happen if and only if you are a winning player.
