1. Take a pen and paper.
2. Write NON-STOP for the next 10 minutes. Start writing freely and spontaneously about the subject of your choice without stopping to make corrections. Don’t take your pen/pencil off the page. Grammar, spelling, and punctuation don't matter. If you run out of words/ideas, or get "stuck" in any way, keep on writing; either write nonsense words or “What could I write now? The topic reminds me…” until you get back “on stream”.
3. When you have finished writing, read your text and find meaningful and interesting ideas and thoughts. Continue working with them.
