I don't know what you second line means, but I would continue working. Possibly reduced hours, but still working.
If you’re already doing the thing you would do if you could do anything, do you still feel the need for “enough money” to walk out and go do it. I think, and some other posters seem to agree, that the answer is a qualified no.
What if your best friend were already doing his thing? Would you feel the urge to send me to talk to him, or is he good?
