I need a filing system for my brain.

Since I have had this great idea to try and get some extra money by crocheting, I have really started getting the creative juices flowing. So much so that I don't sleep sometimes...ugh!  What's even worse is that I will have this brilliant idea and after arguing with kids and cleaning up someone else's mess...I have forgotten my brilliance.  Let's just hope that what I do end up producing is something that makes sense other than me.
