Nelson Mandela, who died in December 2013, would have been 100 years old on Wednesday. He did not let the 27 years he spent in prison break his spirit. There is so much we can learn from him, especially now that the world seems to be imploding. So, here's to a revolutionary leader. May we strive to be like him because there are few people, dead or alive, who can compare to him. Here are a few of his most inspirational quotes.

1. "It always seem impossible until it's done."

2. "Courageous people do not fear forgiving, for the sake of peace."

3. "If you talk to a man in a language he understands, that goes to his head. If you talk to him in his language, that goes to his heart."

4. "Live life as though nobody is watching, and express yourself as though everyone is listening."

5. "Do not judge me by my successes, judge me by how many times I fell down and got back up again."
