Stand alone when it is to your benefit, with others when it is to your advantage, and with everyone when it is to your empowerment.
Water is soft, but can maneuver any obstacle; be shrewd, and be gentle, and you too will be able to do likewise.
Knowing what to say is sense, when to say it is intelligence, how to say it is wisdom, why and how to say it is enlightenment.
Be wise enough to learn from the past, shrewd enough to capitalize on the present, and clever enough to prepare for the future.
Learn from acquaintances, and you are clever; from friends, and you are intelligent; from enemies, and you are shrewd; but learn from all, and you are wise.
An ounce of wisdom is worth more than a pound of knowledge.
A shrewd enemy will teach you more than a foolish friend.
The strong overcome their opponents, the mighty crush them, the shrewd outwit them, the cowardly hide from them, but the enlightened transcend them.
