The CV thing - you're right to not let it stop you BUT I really think you should have an answer ready for a future job interview. If you can find a part time job that sounds okay (i.e. ideally not bar work or whatever, though you're young enough (right?) for that to be fine too) then it might make a big difference. Or maybe some kind of course? The OU does some short courses which really don't take a lot of time but it'd look like you were improving yourself.

Bear in mind that if you play 30 hours poker per week as your "job", you're unlikely to want to do it in your free time, so you'll probably have more time available for studying/working than you think.
