Seneca

There is nothing which persevering effort and unceasing and diligent care can not accomplish.

To wish well is part of becoming well.

We can be thankful to a friend for a few acres, or a little money; and yet for the freedom and command of the whole earth, and for the great benefits of our being, our life, health, and reason, we look upon ourselves as under no obligation.

We should give as we would receive, cheerfully, quickly, and without hesitation; for there is no grace in a benefit that sticks to the fingers.

Where silence is not allowed, what then is permissible?

We all sorely complain of the shortness of time, and yet have much more than we know what to do with. Our lives are either spent in doing nothing at all, or in doing nothing to the purpose, or in doing nothing that we ought to do. We are always complaining that our days are few, and acting as though there would be no end of them.

He who seeks wisdom is a wise man; he who thinks he has found it is mad.

It is not the man who has too little, but the man who craves more, that is poor.

Diligence is a very great help even to a mediocre intelligence. -Diligentia maximum etiam mediocris ingeni subsidium

Do not ask for what you will wish you had not got.
