This all sounds very familiar. I also built a SaaS for small business owners in France (professional filesharing) but I realized I didn't care enough about the product and the audience I was serving (among other problems) I even wrote a post-mortem here: http://www.sparklewise.com/post-mortem-5-mistakes-i-made-with-my-first-online-product/ http://www.sparklewise.com/post-mortem-5-mistakes-i-made-wit... For me, caring about the product and the people you're serving is the most important thing. Don't choose a project because it sounds like a good idea, but choose a project because it's a part of a bigger goal, a bigger mission. However, there's also something to be said for persistence and not giving up at the first obstacle. Finding out where the limit lies is not easy.
