Don't do it.

I think sometimes people don't realize that it is WORK that sucks, not their particular job. Making poker your job would be a doubly-bad move becuase it will take one of your favorite hobbies (which you probably like for as much as any other reason, becuase you are the boss, you play and stop when you want) and turn it into WORK.

Go to a career counselor, and brainstorm about career choices, and make a leap somewhere else maybe, but not poker. Keep it a hobby - thats why its awesome.
