I haven't read every message in this thread, so, if someone has already pointed this out, sorry to repeat it, but there are two things you need to consider:
1. At your current skill level, are you earning money or bleeding it? Keep track of your bankroll over the course of 12 months and see if you're plus or minus. Then play every day for another 12 months and see how your balance is at the end of it. Analyze how you get beaten and by whom. *Then* consider going pro if all the signs are favourable.
2. As a pro, on your 200th straight day of playing for six hours, you might decide you don't want to play today. Well, bzzzt!--sorry, but it's your job, so you *have* to. You have to know whether you're capable of playing, and playing well, when the game is not fun but feels like a drudgery.
BTW, bragging about how much money someone earns as a pro only sets up people for unrealistic expectations, because IMO very few people have the right mentality and makeup to succeed as pros.
For the record, I'm happily amateur and have no plans for turning pro.
