I have worked from home off and on for years, and this is pretty good advice. The most important is the dedicated space with a door that closes. So you still "go to work", just with a very short commute. A few other things that I have found helpful:

  - When you're in your office, you're at work, working.
  - When you're not in your office, you're at home, not working.
  - Work in 48 minute bursts, then take a break.
  - Only check email & voice mail during your 12 minutes off.
  - Put internet and work on 2 different machines (if possible).
  - I prefer radio over pre-recorded music; it reminds me I'm not alone.
  - Eat lunch out with a friend several times per week.
  - Eat home meals away from your office.
  - If you're local, go in to the office once per week.
  - If you're not local, go to the office several days per month.
  - Dinner with SO every night, no matter what you're working on.
  - A regular schedule of sleep, meals, exercise, and work makes things easier.
