Keys To Kindness

Someone reminded me that there are three keys to kindness, and they are not what I thought they were.  Here are the keys:

Sleep enough

Eat properly

Exercise

When I do these three things in my daily routines, I seem to be a nicer, kinder, less judgmental person.  When I am a slug, eat junk, and stay up to late, I am not so very nice.  How about you?
