You feel your strength in the experience of pain.

It is the same with those who criticize. They desire our blood not our pain. But still I must achieve I must seek truth in all things. I must endure for the power I was sent forth, for the world for the children. But have mercy, for I've been bleeding a long time now.

The most important lesson that man can learn from life, is not that there is pain in this world, but that it is possible for him to transmute it into joy.

Whose heart the accustom'd sight of death makes hard.

Pain pays the income of each precious thing.

I learn from my mistakes. It's a very painful way to learn, but without pain, the old saying is, there's no gain.
