Do not try to lead men who are unwilling to follow you; if their heart is not in it, you will never find the old spirit or the old courage.

In my opinion, at least, the splendid achievements of Alexander are the clearest possible proof that neither strength of body, nor noble blood, nor success in war even greater than Alexander's own... that none of these things, I say, can make a man happy, unless he can win one more victory in addition to those the world thinks so great---the victory over himself.

It is more disgraceful for a king to tell lies than anyone else.

~ Arrian

Most people, if they know they have done wrong, foolishly suppose they can conceal their error by defending it, and finding a justification for it; but in my belief there is only one medicine for an evil deed, and that is for the guilty man to admit his guilt and show that he is sorry for it. Such an admission will make the consequences easier for the victim to bear, and the guilty man himself, by plainly showing his distress at former transgressions, will find good grounds of hope for avoiding similar transgressions in the future.
