There is something utterly delightful about the idea that you don't have to know exactly where you are going when you start a creative project. The important thing is just to start and trust in the creative process to get you where you need to be. I suppose it is a lesson in surrendering.
I'm not sure I realised that you could simply begin a story and let it lead where it may. I did learn that you can paint this way - any one who has had a go at intuitive painting will know exactly what I am talking about.
If you haven't you might want to check out two of my favourite teachers of intuitive painting, Alena Hennessy and Flora Bowley. Even if you don't fancy painting yourself it is a fascinating thing to watch Flora Bowley's paintings emerge - you can see her in action here. And she explains her whole process in her book Brave Intuitive Painting. Love it.
