This may sound naive but has anyone got any advice or links to advice on the best way to find real problems to solve, big or small. Preferably small, though because with the big ones its often harder to tell whether they are something that people really want. I'm looking for a way of finding the kinds of things where its relatively easy to tell whether they have a good chance of making some money right now. Its a tall order,I know but you never know what people know until you ask.
