I would say the most important thing is a combination of two things:
1: Work on something that you yourself or your users want to exist. Don't think about what others might want. Make something that you consider pretty cool shit. Or something your users are asking for. Something where you or your users say "OMG when this is ready I will fricking love using it! I can't wait!".
2: Most founders, me included, often get stifled. They stop putting time into their project because they think it is just a dream. Remember that all amazing things have been built by people just like you. And to keep putting time into building something that you yourself or your users want.
