You must guard, too, against certain small desires which are common in daily life. Never wish to shine, or to appear clever; have no desire to speak. It is well to speak little; better still to say nothing, unless you are quite sure that what you wish to say is true, kind and helpful. Before speaking think carefully whether what you are going to say has those three qualities; if it has not, do not say it.
