As I sit waiting for my flight, I am recalling the words of a former principal who said two things that really made sense:
Number 1: You can't save the world, just save the ones you can.
(His advice to me when I would get upset about not reaching every student.)
Number 2: Take care of your family first. You can't take care of ours (school children) if you are worried about what is going on at home.
This guy was pretty smart.
