Most of what I really need to know about how to live and what to do and how to be I learned in kindergarten. Wisdom was not at the top of the graduate-school mountain, but there in the sandpile at Sunday School. These are the things I learned:

Share everything.
Play fair.
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.
Flush.
Wash your hands after you use the bathroom.
Warm cookies and cold milk are good for you.
Live 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 world, watch out for traffic, hold hands, and stick together.
Be aware of wonder.
