What do your friends and family do? Find someone you know who is really good at what they do, in a non-programming field. Ask about their workflow, and try to find the areas where they could have better tools. Then start to build those tools.

The most innovative and useful ideas seem to come from a mix of high level domain expertise, and high level technical ability. If you don't have both of those, find someone who has the piece you are missing.

Edit: sorry, assumed you were op.
