My all-time favorite quote:
"An ounce of prevention is worth a pound of cure." - Benjamin Franklin
And my second all-time favorite quote:
"It is easier to build strong children than to repair broken men." - Frederick Douglass
First time I read the second one, it brought tears to my eyes. SO much horror in this society could be prevented if only so many children were not horribly abused and neglected...
Speaking of quotes that make me tear up:
"Only when the last tree has died
and the last river been poisoned
and the last fish been caught
will we realize we cannot eat money."
Cree Indian Proverb
