As a child of the sixties, and also a boxing fan, Muhammad Ali was always going to be one of my biggest heroes. I loved his charisma, the brashness, the courage, and the sublime boxing skills all of which made him "the Greatest".  

But it was his wisdom, and what he did outside of the ring that made him into one of the most inspiring leaders that I have ever seen.  

Here are 50 pieces of wisdom from Ali which we could all look to follow which would make the world a better place.
