There are some nice thoughts here but I'd like to know what the plan is to survive. Its certainly possible to make it but I feel like this is glorifying a situation that most people once on the other side of the fence are going to be under stress and realize things are not necessarily so rosy. You have savings - great step. You have some things your working on - great step. Now how do you start making just enough money before your runway ends and you have to either go back to a job or start eating into your own time to do consulting (which is basically employment from my perspective).
Ill admit Im a relatively risk averse person but Id say the best plan is the 1 step plan where the time you are spending on your own business becomes more profitable than going to work - easier said than done but thats my 2 cents.
