I have been doing my morning pages this week and I have to say I am feeling a lot more creative and a lot more positive. I first started when I was doing the Artists Way (Julia Cameron). Basically you write three pages of A4 longhand when you first wake up in the morning. Just anything that comes into your head - kind of like diary but not.
I write all kinds of things in mine - neuroses, dreams, lists, moans, wishes, poems, memoirs - whatever comes to me. The aim is to just keep writing until you fill up three pages. The idea is to declutter your mind, which will allow your creative juices to flow more freely. And it doe really work - I am a lot more productive when I do them, they make me more positive and in turn more open to change.
Julia Cameron is not alone in listing this as a basic vital tool to aid the creative mind - in recent years I have seen it cited in many creative and self-help books. A spiritual friend of mine who I described it to summed it up exactly - "you're just doing your stuff aren't you, getting it out so then you can get on with your day unhindered."
