If I stopped getting paid for what I did, I wouldn't drop it all instantly. But it depends.
If it's something that I don't enjoy doing, then I'll drop it instantly. No problem.
But if it's something that I absolutely love doing and am appreciated for and known for, then I would do it no matter what. Maybe I'll slow down at first, but I won't drop it altogether.
Yup, personal interest in doing something also factors in heavily for doing it when there is no money involved ;)
