It is the quality of your life that matters, not its length.

The impediment to action advances action. What stands in the way becomes the way.

If you carve without ceasing, even metal and stone can be engraved.

-- Xunzi

-- Mencius

What does not kill me makes me stronger.

-- Friedrich Nietzsche
