Prudence is sometimes stretched too far, until it blocks the road of progress.

Sincerity is glass, discretion is diamond.

He who is not a bird should not build his nest over abysses.

If thou thinkest twice before thou speakest once, thou wilt speak twice the better for it.

Be moderate in prosperity, prudent in adversity.

Consider the little mouse, how sagacious an animal it is which never entrusts its life to one hole only.

It is well to moor your bark with two anchors.

Never exceed your rights, and they will soon become unlimited.

Reveal not every secret you have to a friend, for how can you tell but that friend may hereafter become an enemy. And bring not all the mischief you are able to do upon an enemy, for he may one day become your friend.

We are prudent people. We are afraid to let go of our petty reality in order to grasp at a great shadow.
