Good Ideas.

Personally, I do not write or record my ideas. It could be a good thing to try. You could carry a small journal, or whatever your comfortable with and when you have a good idea write it down. You could even put your idea in the notepad on your phone! Later that day or week you could look back at them and elaborate more into detail about the idea.  Your idea(s) could make you money one day or just make you happy. 

I might carry a small notebook in my purse and just give it a try one week, at the end of the week I'll review them and see what I came up with!
