In no particular order:

  • sleep (more, up to a point, is better. regular & quality is key)
  • exercise (as much as possible)
  • medication (to maintain a baseline)
  • food (reasonable habits)
  • hormones (I just have to be prepared)
  • balance of solitude & socializing
  • light (natural best, fluorescent worst)
  • length of to-do list (shorter better)

With the coming of fall, I’ve had to add more light, especially in the morning, and deliberate exercise.  I’m a little nervous about the next few months (now thru Feb), so I’m being extra-careful with all the variables that I have any control over, and with how I think about my moods.  Wish me luck.
