I'll shoot you an email too, but I'm building a product. I started it 6 months before quitting, and by the time I put in my resignation I had a good amount of users and steady growth that's only continued since.
At first I did some consulting to help with expenses, but eventually I dropped that work so I could focus better on the product. But I also reveled a bit too much in the initial freedom after quitting, and took way longer to get the product to the next stage (which I'm now at) where I've got good features my users will pay for. So now I actually just accepted a salaried job again, as I only saved up enough for <1 year's expenses (definitely save up more :) ).
Overall I've learned more in these past months about business, product development, software development, managing people and finances than I would've in a lifetime working for someone else -- and that was my real goal. So overall it's been a success, and next time I do this I imagine I'll be much more effective.
