The Inner Citadel

No one is born with a steel backbone, we have to forge it ourselves. We craft our spiritual strength through physical exercise and our physical hardiness through mental practice. The Stoics called the inner citadel that fortress inside of us that no external adversity can ever break down. To Roosevelt, life was like an arena, and he was a gladiator. You'll have far better luck toughening yourself up than you ever will trying to take the teeth out of a world indifferent to your existence.
