I wish you the best of luck man. Don't eat, don't sleep, just keep plugging away. It's actually better that you have no money saved up... it'll make you work that much harder.
Just work your ass off so you never have to go BACK to a day job.
Good job on having your bills so low. If you know how to code you could get a freelance that you could do in a day for $300. Just has to be the right niche of a job and you have to be proficient at coding. But wouldn't be two hard. A lot of people would pay a lot of money for the right things.
