Ask HN: How to pick a startup idea

As a developer, I find it easy to pick an idea and build an MVP/prototype. When you have several ideas, how do u select which one to work on?

Some criteria I came up with are: 1. Passion for the idea (cant fake it!) 2. Market opportunity (its hard to figure this out for consumer mobile apps) 3. Team/market fit 4. Funding possibility for the idea Any other??

Also, when do u give up on an idea and move to the next one?? In pre-funding phase, its hard to figure this out.
