“If you understand others you are smart.
If you understand yourself you are illuminated.
If you overcome others you are powerful.
If you overcome yourself you have strength.
If you know how to be satisfied you are rich.
If you can act with vigor, you have a will.
If you don’t lose your objectives you can be long-lasting.
If you die without loss, you are eternal.”
—Lao Tzu (Tao Te Ching)
