Tao Te Ching: Chapter 33

Those who understand others are intelligent,
Those who understand themselves are enlightened.
To be victorious over others is to be powerful,
To be victorious over oneself is to be invincible.
Those who seek wealth lose themselves in riches,
Those who seek power become slaves to ambition,
Only those who are true to their principles endure,
And those who die but are not forgotten live on.

Lao-tzu (c.6th BCE)
