Loose Thread

So as usual, I had a story in my head. And because I didn't make the effort to capture it, it flew away. Liz Gilbert said in her TED gig that you have to take hold of the that loose end of an idea, tug and pull it towards you. It will fall away like a loose thread from a knitted sweater, and you have to be quick to keep tugging to gather the thread in to a ball of creative energy. Otherwise… the idea, the story will end up in a messy heap on the floor, and you will wail in despair when you realise it could've been gathered and turned into something possibly beautiful.

What's stopping me then?
