To be proud of learning is the greatest ignorance.

Nothing is so good for an ignorant man as silence; and if he was sensible of this he would not be ignorant.

Ignorance, when voluntary, is criminal, and a man may be properly charged with that evil which he neglected or refused to learn how to prevent.

By ignorance is pride increased; those must assume who know the least.

It is better to be a beggar than ignorant; for a beggar only wants money, but an ignorant person wants humanity.

To be idle requires a strong sense of personal identity.

Go to the ant, thou sluggard, learn to live, and by her busy ways, reform thine own.

Rather do what is nothing in the purpose than to be idle, that the devil may find thee doing. The bird that sits is easily shot when the fliers escape the fowler. Idleness is the Dead Sea that swallows all the virtues, and is the self-made sepulcher of a living man.

It is not the hours we put in on the job, it is what we put into the hours that counts.

Sloth makes all things difficult, but industry, all things easy. He that rises late must trot all day, and shall scarce overtake his business at night, while laziness travels so slowly that poverty soon overtakes him.
