A realization

I've had an idea today, well not just one but many. And as I go to write or commit to the idea--like if it's one about drawing a design about how to better the world--it flies out of my mind just as fast as it comes. Trying to get the idea back is just as hard as trying to write it down before it leaves the forefront of my mind. So my realization is that any other revelations I have about anything will soon be gone and therefore must not of been good ideas for my mind to quickly to dismiss them...or the other alternative is that my mind thinks too fast...which more often than not is the case.
