To say Muhammad Ali had a way with words is something of an understatement.

His press conferences and interviews redefined the way people saw boxers – and to a larger extent, professional athletes in general – and made sportswriters everywhere reconsider their own turns of phrase.

And while Ali was as known for the comical insults he dished to opponents as he was for the self-aggrandizing brags he tossed out about himself, he was also a fiercely intelligent and introspective man. Here are some of his best quotes that are appropriate for everyone, whether or not they consider themselves The Greatest.

The man who has no imagination has no wings.

There are no pleasures in a fight, but some of my fights have been a pleasure to win.

Friendship is the hardest thing in the world to explain. It’s not something you learn in school. But if you haven’t learned the meaning of friendship, you really haven’t learned anything.

Often it isn’t the mountains ahead that wear you out, it’s the little pebble in your shoe.

The service you do for others is the rent you pay for your room here on Earth.

I never thought of losing, but now that it’s happened, the only thing is to do it right. That’s my obligation to all the people who believe in me. We all have to take defeats in life.

My soul has grown over the years, and some of my views have changed. As long as I am alive, I will continue to try to understand more because the work of the heart is never done.

Age is whatever you think it is. You are as old as you think you are.
