From the very start of my career, it was clear to me that achievement was built on discipline.

Joe Louis is the hardest puncher that I've ever seen... He's a good man. Anyone who plans on beating him had better know what they're doing.

I received a letter from the Reich Ministry of Sports. They want me to split from Joe Jacobs, my manager since 1928.... I really need Joe Jacobs. I owe all my success in America to him.

I said to myself, 'You're a man from a humble background, what you didn't learn in school, you'll learn now. Catch up.

Just imagine if I would have come back to Germany with a victory. I had nothing to do with the Nazis, but they would have given me a medal. After the war I might have been considered a war criminal.

I had a happy marriage and a nice wife. I accomplished everything you can. What more can you want?
