[Scenario]

Instead of making things which have already been released, imagine some of your own ideas. On occasion, I will sit down and brainstorm, jotting down the first things which come to my mind. If I'm not sure that the idea has already been thought of and released, I'll use the forums search function. If it's been released, usually I'll take a look at it and realize I should pursue another idea. If not, then I will continue to work on that idea. At least then you can say you "thought of the idea".
