Amazing stuff. I think I'm in the boat as you OP except I just can't get myself to commit to a project since 1) no idea if it works or is unique 2) look for better opportunity and spend time doing LC/apply for job.

There is only so many hours after work.

> Once you’ve validated your idea,

Could you really break this down. I feel you overlooked this part. How do you filter through tons of ideas into idea that for sure or has good chance for success. For example, to build a yet another crypto exchange is both super technical and far too regulated. What is a known strategy how founder/dev nail down and commit to a project?
