That was my greatest achievement because I was just a 19-year-old boy who thought dreams could never come true.

I don't even think about a retirement program because I'm working for the Lord, for the Almighty. And even thought the Lord's pay isn't very high, his retirement program is, you might say, out of this world.

In boxing, I had a lot of fear. Fear was good. But, for the first time, in the bout with Muhammad Ali, I didn't have any fear. I thought, 'This is easy. This is what I've been waiting for'. No fear at all. No nervousness. And I lost.

Not much happens without a dream. And for something great to happen, there must be a great dream. Behind every great achievement is a dreamer of great dreams. Much more than a dreamer is required to bring it to reality; but the dream must be there first.

He who would accomplish little must sacrifice little; he who would accomplish much must sacrifice much
