I see some good advice on this thread so a followup question.

I'm about to quit my job with the aim of starting up my own company. I don't have a lot of non-tech contacts - i.e. potential customers and angel investors. That is my biggest worry.

I can't really bootstrap while on the job since I am currently in a large corporate job where the company owns everything I dream up.

So .. while I agree with all the advice about not quitting a job until one has another one lined up (I've given the same advice to others) ... I am about to go against this advice myself.

Any words of advice on how to manage this? Am I bonkers? Some stats ... have 6 months of living costs in liquid savings. No kids. Going to be leaving a job that pays north of 120K (which is not much in elite companies it seems).
