I Have Ideas And I Need Somewhere to Put Them

I have a lot of ideas!

Creative concepts run through my head throughout the day constantly. But I have nowhere to put them. I think I need to start walking around with a notebook. That way if I'm walking down the street and come up with something I think is neat, I can stop and write it in down in my notebook.

However, a notebook might not work. I have a hard time organizing my ideas. If I had a notebook, it would be scattered with so many different concepts and no familiar thread. I would need something like a binder.

A binder would be great because I could organize my ideas by sections and categories. The only trouble with a binder is that it would be heavy and bulky to carry around.

I need some place to put my ideas other than letting them sit in my brain.

Any suggestions?
