Here's what I have.
1. Whiteboard tasks for the week, w. daily assignments
2. Check emails once an hour
3. Set default page in FF as a blank page(as opposed to Gmail, Reader, etc.)
4. Tea, not coffee. Cup of water on hand at all times.
5. 7 pull ups each time I use the bathroom.
Equipment-wise, multiple screens tend to help. A good chair too.
