Here are just a few of my favorites that I turn to when I need some motivation
"Some people dream of success while others wake up and work hard at it"
"I cannot give you the formula for success, but I can give you the formula for failure--which is:Try to please everybody"
"The best way to prepare for life is to begin to live"
"When one door of happiness closes, another opens, but often we look so long at the closed door that we do not see the one that has been opened for us"
"There is only one way to happiness, and that is to cease worrying things which are beyond the power of our will"
"Happy are those who dream dreams and are ready to pay the price to make them come true"
