When Do You Quit a Job?

When i started performing at growndings, i felt like a leo. It sort of fuls you to get a few laughs a and then it buys you enough to go in again the next week. If you were bombing every time it would be different, you'd be like, a shit, this isn't for you. But the scary thing even for me and standup was, when do you get rid of the job? And try to realize the pressures when you say, 'I just want to do this now'
