I don't think anyone like their 9-5 jobs. However, I still think it's prudent to at least have a 20 hour a week job to pay the essentials. Poker is hard enough without going into the poker rooms saying in the back of your mind "gotta win tonight-gotta pay the rent...).
Having some kind of guaranteed cash coming in is psychologically beneficial. Scared money loses because you tense up and don't make moves you would make if you were in a position of stength (strength from the aspect of your life in general).
But for those who burn their bridges and really play with no support structure, props to you.
I often wonder why is that when people decide to go pro that they don't at least look for a part time job that they enjoy for maybe 20 hours a week. Do they actually hate working that much?
I very much agree with your post. Playing with scared money can't be a good thing. When I do decide to go pro I will no doubt take on a part time profession to fill in the time and do something that I really enjoy like web development or a graphics artist etc. and having a little bit left over to pay for the essentials without having to rely on strictly poker winnings.
