Great idea man, dump that bitch she's eating your food, food that could help to get you big! Agreed about the job aswell it'll just take up time you could be spending at the gym doing machine flyes, leg extensions & cable curls. With regards to your mate scoring you all the gear, I wouldn't bother paying him back. He's a friend so he should be buying you all your shit, afterall what are friends for. I'd keep the car though, if money gets tight and you get booted out of the hotel room you could always live in it and could be a base for you to start homersexual tricking out of.
All in all mate, good job. Glad to see you've woken up and are starting to live the dream
