If anything affects your eye, you hasten to have it removed; if anything affects your mind, you postpone the cure for a year.
[Lat., Quae laedunt oculum festinas demere; si quid
Est animum, differs curandi tempus in annum.]
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.
