The most valuable gift of nature to man is not talent, not even genius, but temperament and character. If you have both talent and character, the world will belong to you, if you succeed in making talent the servant, and not the master, of your character.
The successful man is not the one who seeks opportunities, but the one who knows how to seize them by the forelock when they present themselves. The great diplomatist is not the one who creates events, but the one who foresees them and knows best how to profit by them.
A man may be very clever without being very successful. This happens when he has more talent than character; but when a man is very successful, never be jealous of him, for you may take it for absolutely granted that he possesses qualities which account for his success.
Envy is the worst of evils, the one that pays least, because it never excites pity in the breast of anyone, and because it causes you to waste lots of time concerning yourself about other people's business instead of spending it all minding your own.
Watch your children most carefully, for when they are ten or twelve years of age you may detect in them signs of defects, or even vices, which, if developed, instead of checked at once, may prove to be their ruin.
