My favorites:

"Depression is merely anger without enthusiam" (I love this one because I suffer from depression. 2 years without meds! Yea, for me!!!!)


"Today's mighty oak is just yesterday's nut that held it's ground"

"Watch your thoughts; they become words.
Watch your words; they become actions.
Watch your actions; they become habits.
Watch your habits; they become character.
Watch your character; it becomes your destiny. "
