It is inevitable that some defeat will enter even the most victorious life. The human spirit is never finished when it is defeated... it is finished when it surrenders.

The human spirit needs to accomplish, to achieve, to triumph to be happy.

Surefire things are deadening to the human spirit.

I guess you can't live at full-on intensity forever. Lying on the bed of my cell in the dark, trembling, waiting for the soldiers to come in and shoot me - you just can't keep doing that. There's something in the human spirit that won't let you live that way.

This world… belongs to the strong, my friend! The ritual of our existence is based on the strong getting stronger by devouring the weak.

Enjoyment is an incredible energizer to the human spirit.
