"I am the greatest, I said that..." - Quote by Muhammad Ali

“A man who views the world the same at fifty as he did at twenty has wasted thirty years of his life.”

“Unknown Make new friends but keep the old ones; one is silver and the other's gold.”

“People don't realize what they had till it's gone. Like President Kennedy, there was no one like him, the Beatles, and my man Elvis Presley. I was the Elvis of boxing.”

“I still think I am the greatest.”

“I am so mean I've handcuffed lightnin' and thrown thunder in jail.”

“Confidence is that feeling by which the mind embarks in great and honorable courses with a sure hope and trust in itself.”

“If you know you are right, stay the course even though the whole world seems to be against you and everyone you know questions your judgment. When you prevail--and you eventually will if you stick to the job--they will all tell you that they knew all along you could do it.”

“Nothing was ever accomplished by anyone who said 'It can't be done.'”

“Just because you fail once, doesn't mean you're gonna fail at everything. Keep trying, hold on, and always, always, always believe in yourself, because if you don't, then who will, sweetie? So keep your head high, keep your chin up, and most importantly, keep smiling, because life's a beautiful thing and there's so much to smile about.”
