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?
Most successful businesses take years to build (at which point they suddenly look like overnight successes to outside observers). But you can definitely prove out the concept for a product (or several) in six months -- and decide then if it's worth continuing to pursue, or if it's time to go back to a paying job.
If that's not what you had in mind, then you have to state where the goalposts are.
Maybe your constraints (e.g., doing it alone as a solo engineer) are the true blocker.
