I never quit trying. I never felt that I didn't have a chance to win.

I've always made a total effort, even when the odds seemed entirely against me. I never quit trying; I never felt that I didn't have a chance to win.

Winners never quit and quitters never win.

You can win it in the late innings if you never quit.

You can never quit. Winners never quit, and quitters never win.

Americans never quit.
