Wow!
Congratulations on your decision! It sounds like you've got a good plan in place, and you're about the best spot anyone could hope to be in taking a shot at something like this (Job situation, expenses, etc..), all things considered.
I think you've got what it takes to make it man. just watch out for deviation (of the human variety); and keep an eye on the burnout factor. Also, I'd have to say, poker players probably don't make the best co-workers (while you're 'working' with them) so stay in touch with friends and family too, if you can, outside the cardroom.
Stick to your convictions with this and you will be successful!
Can't wait to see some hands being posted under Jesse8888 again...
Good luck!
