The Weight of an Idea or Initiative

Ideas generally sit in my brain for some time before I work on them. There's been one big idea in my brain for some time now, and it just hasn't taken enough shape for clear direction yet. The idea now is somewhat like a brain cloud, and at sometime it will turn to rain and nurture the birth of a good idea. I love the brain action that happens with idea development. I find it very interesting and want to learn more about it.
