We're trapped in a world that's troubled with pain. As long as a man has the strength to dream, he can redeem his soul and fly.

What I know for sure is that there is no strength without challenge, adversity, resistance, and often pain.

Whoever, at any time, has undertaken to build a new heaven has found the strength for it in his own hell.

Let me not beg for the stilling of my pain but for the heart to conquer it.

Sometimes when you're treated unfairly it makes you stronger and more determined. I admire that kind of strength. People who have it take a stand and put their blood and soul into what they believe.

The discipline of suffering, of great suffering- do you not know that only this discipline has created all enhancements of man so far? That tension of the soul in unhappiness which cultivates its strength, its shudders face to face with great ruin, its inventiveness and courage in enduring, preserving, interpreting, and exploiting suffering, and whatever has been granted to it of profundity, secret, mask, spirit, cunning, greatness - was it not granted to it through suffering, through the discipline of great suffering?
