Don't try to come up with an idea. Instead find a group of people that are into something(preferably something you are into as well) see if they have any problems or friction with the thing they are into. Try to offer them a solution for their problem. If they start to eagerly use your solution, try to generalize your solution for larger and larger groups of people.
