Fall in love with the pain -- no one actually wants to use your app because it's fun (unless you are a game obviously), so figure out what need you are solving and then relentlessly focus on eliminating that ONE pain. The only other exception to this is if you have a complex pain or series of pains that naturally fall into a workflow--it might be better to support them all in one app vs. several separate apps.
Take a closer look at apps you respect and use everyday. Integrate award-winning apps into your daily life. Study them and figure out what they are doing that makes them so awesome. Then apply that learning to your app.
