What I will say may be old. But that's what I feel everyday I use any piece of software/service. Since I did some startups before years ago. I may just say something only obvious to anyone who have tried them.

1. What kind of stuff do you feel pain?

2. Do all the existing solutions on the market solve that pain?

3. Can you come up something that may be better so users will put their time and money on your idea?

4. Fail, why?

5. Traction, why?

6. Repeat, continue, 1,2,3 [4|5] until you decide to leave the industry.
