Eloquent. Colorful. Controversial. Inspiring. These are only a handful of descriptors that come to mind when Mohammad Ali’s name is mentioned. Known as “The Greatest,” he reached his peak in the 1970s and was among the most recognizable faces on Earth. This past Friday, the three-time boxing champion died in a Phoenix hospital where he was being treated for a respiratory issue.

Here are ten of my favorite quotations from Mohammad Ali:

He who is not courageous enough to take risks will accomplish nothing in life.

Service to others is the rent you pay for your room here on earth.

It isn’t the mountains ahead to climb that wear you out; it’s the pebble in your shoe.

Silence is golden when you can’t think of a good answer.

Don’t count the days, make the days count.

Impossible is just a big word thrown around by small men who find it easier to live in the world they’ve been given than to explore the power they have to change it. Impossible is not a fact. It’s an opinion. Impossible is not a declaration. It’s a dare. Impossible is potential. Impossible is temporary. Impossible is nothing.

Champions aren’t made in gyms. Champions are made from something they have deep inside them-a desire, a dream, a vision. They have to have the skill, and the will. But the will must be stronger than the skill.

The best way to make your dreams come true is to wake up.

To be a great champion you must believe you are the best. If you’re not, pretend you are.

The man with no imagination has no wings.
