this is a great way to go.

i left my job with no savings and intending to do the same thing, because i was just not happy with my position at my new employer.

within three months i was completely broke, but with a github account with hundreds of commits.. and then my old boss from my second-to-last job called, and offered me job back, at a huge raise, and allowing me to work remotely, and pursue my own codebase/startup dream on the side.

quitting for the right reasons can have wonderful side benefits. :)
