1. The freewrite is designed to produce spontaneously-generated language that has the allure and excitement of something improvised that is free from editorial override. This may even be something that is inappropriate or troubling. The whole of the freewrite should seem blurted.

2. The key to freewriting is to keep the mind moving. This is the main thing. Do not spend time getting hung up on what you are writing. Try to write at the same speed as you can think. Some delay might be necessary in order for the mind to momentarily get its bearings.

3. The above may produce a fine stream of verbal vomit. That's OK. Trust yourself to edit the drivel later.

4. In order to reduce the amount of drivel, focus on concrete (physical) language. Try to avoid the kind of vacuous talk that might occur during a cell phone conversation where you are rehearsing your activites or plans for the day. Freewriting should be non-programmatic.

Remember: the ultimate aim is to produce some startling language or insight that will inform a piece later. Let yourself go. Often nearly 90% of the verbiage that one generates during a freewrite is useless. But the useful bits often are the turns of phrase and one-liners that are memorable because they are freshly wrought on the spot.
