Nothing is so strong as gentleness, and nothing is so gentle as true strength.
Fire is the test of gold; adversity, of strong men.
Strength does not come from physical capacity. It comes from an indomitable will.
Be faithful in small things because it is in them that your strength lies.
Let me tell you the secret that has led me to my goal: my strength lies solely in my tenacity.
Nothing is so strong as gentleness. Nothing is so gentle as real strength.
