I have the opposite problem. I have a genius idea, and I start to research it.

I find a company that actually built a solid product, dangit this is really good. They appear to have executed well, but they failed, or went nowhere, heck the app is still out there. Maybe they are even chugging along but its a smaller business even with a better product than I would have been able to build. Had I been a founder of the product, I would be questioning staying.

Then I also find sometimes I was doing it all wrong and the world has moved past my notions of products. I think there's a market opportunity because I don't realize that the rest of the world is already cool using a $15 plant hygrometer bluetooth device which can also keep track of your medicine or food in your cooler, my notion of the value of something is skewed by western costs
