It belongs to human nature to hate those you have injured. — Tacitus. Roman historian and senator (56–120) Anger
All enterprises that are entered into with indiscreet zeal may be pursued with great vigor at first, but are sure to collapse in the end.
Abuse, if you slight it, will gradually die away; but if you show yourself irritated, you will be thought to have deserved it.
Fear is not in the habit of speaking truth; when perfect sincerity is expected, perfect freedom must be allowed; nor has anyone who is apt to be angry when he hears the truth any cause to wonder that he does not hear it.
