Of all the cankers of human happiness, none corrodes it with so silent, yet so baneful, a tooth, as indolence.

Never trouble another for what you can do yourself

No man will labor for himself who can make another labor for him.

Everything yields to diligence.

Nothing is troublesome that we do willingly.

He who knows best knows how little he knows.

It is while we are young that the habit of industry is formed. If not then, it never is afterwards. The fortune of our lives therefore depends on employing well the short period of our youth.
