Don’t hit people.
Put things back where you found them.
Clean up your own mess.
Don’t take things that aren’t yours.
Say you’re sorry when you hurt somebody.
Wash your hands before you eat.
Warm cookies and cold milk are good for you.
Live a balanced life---learn some and think some and draw and paint and sing and dance and play and Work every day some.
Take a nap every afternoon.
When you go out into the world watch out for the Traffic, hold hands and stick together. Be aware of wonder.
To those I would add the ultimate: First of all, to do no harm.
