Most of what I really need to know about how to live and what to do I learned in 'Preschool'.

Wisdom was not at the top of graduate school mountain, but there in the sand pile at Preschool.

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 & after you flush. Flush. Warm cookies and cold milk are good for you. Live a balanced life - learn some and think some and draw and paint some and sing and dance some and play and work some every day. Take a nap every afternoon. When you go out into the world, watch out for traffic, hold hands and stick together. Be aware of wonder. Author Unknown.
