Story

I realise variants of this question are often asked on HN, so I apologise in advance.

I'm a DevOps/Software Engineer and I've just left my job at a large company you likely know of. In short, the project I was on imploded and management were sociopaths, so I've been in a depressive state for a while. Financially speaking I'm in a good position, so I'd like to allocate 6 months to see if I can build my own thing.

I have a number of ideas, but I'm having a hard time separating the ideas I'd like to build from the ideas that will have paying customers. I don't have any prospective customers yet either. Frankly speaking, I have no experience getting people to hand over their wallet for something.

Am I out of my mind or is this doable?
