Starting a full-time job while still enrolled/dissertating?

I'm within my last year of my way too lengthy social sciences PhD in a US R1 university and am very strongly considering starting a full time industry job and finishing my dissertation while working. I do not need to be on or near campus. I have just grown so cynical about academia, have almost lost my will to keep going, and just generally have nothing to look forward to. I want to make some money and have a life with some purpose again! Of course, I am worried that if I do that I won't finish, but I also wonder if it would give me the oomph I need to just get the dang dissertation DONE. I almost feel like I have no real, concrete reason to finish it right now and I just keep letting it drag out.

Has anyone started working full time while finishing their diss? Any advice?
