What you're explaining is pretty normal. It's also a GOOD thing. The worst thing you can do is start on a project the moment you think of it. It's like the honeymoon period of a relationship, everything looks great, then you hit reality. A really good idea you'll get to those problems and still be passionate enough about the idea to resolve them. If you can get past THAT point, that's when you start working. But you need to put effort into resolving the issues first. If you're giving up before then it's because you're either lazy (sorry!) or not that keen on the idea. You may also need to reassess your expectation of success. I doubt anybody here has had an idea which they 100% knew was going to allow them to retire at 17. Most of the time you have something you think "could" work, or "might be cool". If you can live of your projects, that's a good place to start.
