i don't really have a favourite quote, not one that i've ever stuck with anyway, i've heard things and read them and liked them but none have stuck with me.
however i did just google them and found these...
"You are not fully dressed until you wear a smile."
"Given the choice between the experience of pain and nothing, I would choose pain."
"The man who removes a mountain begins by carrying away small stones. "
“I'm not getting married today. I'm in bed.”
the last one i just thought was funny :)
