My dev skills had atrophied long ago, my career felt like it was at a weird dead-end. I was still very aware of various technologies, but didn't know the syntax of every latest framework.

I still had b2b product ideas, but was never able to raise funding. I built an MVP in 2 weeks, got a co-founder to pay for my beans and rice for the year spent building, getting feedback, and refining. We now have paying users.
