I wouldn't even consider turning pro if I wasn't looking to make at least 100k/year. So let's say I play poker 300 days out of the year, that's $333.33/day. Meh.
In order for me to commit to playing poker professionally longterm, I would need to be making around a quarter mil/year.
To be blunt, a career in poker is stressful, unstable, unhealthy, and socially isolating. Anyone with the illusion that it is easy to make money playing poker fulltime is mistaken. In fact, most people that decide to go pro are unsuccessful because they don't have what it takes. Being a winning player isn't enough. You have to have the discipline to not go on tilt after long losing sessions. You have to have the stamina to multitable for hours on end day after day. And most important of all, you have to have a passion for the game.
