Things I say to my students (to ruin their lives): Never give up. You never really know which idea is the one that's going to fly. Like you, what I've learned is that I'm probably not the best judge. And let's face it, why would you trust others to tell you either? Much of it is luck alone. So it's a numbers game. Trust your gut. FWIW my collection of smart-sounding ten-a-penny platitudes from internet randos: The world is full of genuine problems and people whose lives can be improved. You're probably smart enough to solve at least one of them. Having failed many times makes you an expert. Great ideas are ten a penny. Implementations count. Most people are trying to solve the wrong problems. Pick a hard one that others would be too scared or embarrassed to touch. Do not be seduced by technology. It's a tool, not an end. Do not be seduced by business/money. It's an end, not a method. Good fortune.
