I was out in the fields early this morning walking the dog (pretty idylic scene actually, nature, sunshine etc) and talking to him (like you do) when I had a light bulb moment. You know one of those moments when something seems like the best thing you ever thought of in your life.
Not having a notebook with me (whyever not???) I had to keep the thought in my head until I got home. I managed to do that which isn't at all impressive when you consider that the field I was in is about 50 yards (sorry I'm an old fashioned girl and don't do metres) from my front door and we were on our way home when the lightbulb went on.
Said idea is now written in one of the four notebooks that I keep in my bag along with what I was thinking when the lightbulb illuminated itself. Note how I didn't say "lightbulb went on" twice in 2 sentences - didn't want to repeat myself.
So this brilliant idea is now in the WIP system (God help it) along with a few hundred other things. I just hope that it doesn't get lost in there.
