Abraham Lincoln actually said...

"Always bear in mind that your own resolution to succeed is more important than any other one thing."

"I am not bound to win, but I am bound to be true. I am not bound to succeed, but I am bound to live by the light that I have."

"The best thing about the future is that it comes one day at a time."

"Public sentiment is everything. With public sentiment, nothing can fail; without it nothing can succeed."
