Prewriting Techniques

I enjoy two different prewriting, which are freewriting and the listing methods. I love to use these techniques becauseit allows my thought to flow and to write down any idea that come to my mind. When I use the freewriting technique I don't worry about grammar or punctuation I just let what ever comes to my head flow onto the paper. When using this method I come up with a lot of great ideas that I never knew I had in me. Prewriting gets the blood flowing in me and allows me to just go with the flow. Does anyone else use the same techniques or do is there another one that you use? fell free to express yourself!
