Rules of Sanity

A few days ago, I started the following list, purely for my own amusement. I share it now for yours.

Rules of sanity (in no particular order):

Treat all schedules as works in progress. (This is for your sanity, not other people's.)
Don't plan how you're going to use time you don't have yet.
Do stuff when you have a chance.
Everywhere you go, take with you a book (or two), a notebook (or two), and a writing utensil (or two). After all, you never know when you might get stuck for a half-hour waiting for a train to pass. Even if there haven't been any trains there for 20 years.
Do first that which is most urgent. (But see next item.)
Do first whatever it is you have energy to do.
When the brain cells fail, it's never a mistake to do dishes. (Not quite as valuable now that we have a dishwashing machine. Maybe substitute "do a load of laundry/pick up the living room"?)
When you're too tired to work, sleep.
Go for walks. It's better than strangling people.
Don't put off taking a shower.
When your body informs you that you aren't getting (back) to sleep anytime soon, get up and do something useful.
Always have some nebulous writing project to work on in your spare time. It's the best way to avoid having any. (Spare time, that is.)
Don't break your diet for something you don't really like.
Warm Pero and a bathrobe are the best cure for a headache. Along with Excedrin.
Dark chocolate. Need I say more?

So what are your own personal rules of sanity? Feel free to share!
