I have a lot of ideas that don’t amount to anything. We all do.
When I’m trying to create, I often try a lot of ideas that don’t lead to very much. It’s only when I stumble (it often feels like stumbling) across a unifying concept that the creative work starts to really take shape.
Until then, it’s try an idea, try an idea, try an idea. Because you never know which two, bumping into each other, will show you the unifying concept.
