Life gives nothing to man without labor.
If matters go badly now, they will not always be so.
Whatever you teach, be brief; what is quickly said, the mind readily receives and faithfully retains, everything superfluous runs over as from a full vessel.
The higher the tower, the greater the fall thereof.
Take away the danger and remove the restraint, and wayward nature runs free.
Be prepared to go mad with fixed rule and method.
