I think to ensure success you need to pursue solutions to problems you actually care about. Unless you have significant time or cash resources I don't think you could get far just picking things you think would be good ideas. For instance, I wouldn't last 5 minutes starting a project to help potential or new immigrants, recovering drug addicts, or yacht owners. Even though I think those may be valuable niches for solutions, I have no investment in the outcome. I would have no way of judging progress or success without taking someone else's word for it. I don't think there is any lack of problems you care about if you think hard enough, and if that fails, just take a walk around your neighborhood, your home, your job. Something will piss you off/inspire you soon enough.
