Seneca

No man was ever wise by chance.

It is the power of the mind to be unconquerable.

Life is like a play: it matters not how long it is, but how good it is.

As is a tale, so is life: not how long it is, but how good it is, is what matters.

Until we have begun to compose ourselves, we are but children.

While we are postponing, life speeds by.

Every man is a slave to his own passions.

Anger: an acid that can do more harm to the vessel in which it is stored than to anything on which it is poured.

Associate with those who will make a better man of you. Welcome those whom you yourself can improve. The process is mutual; for men learn while they teach.

For many men, the end of life is not the end of suffering.

What man can you show me who places any value on his time, who sets a daily price on each day, who understands that he is dying daily?

Every day is a new life to a wise man.

No one can be happy who has been thrust out of the way of truth and wanders about through a labyrinth of error.

It is a great thing to know the season for speech and the season for silence.

What is the best way to conquer anger? By forgetting it.

We are often more afraid than hurt; and we suffer more from imagination than from reality.

Leisure without books is death, and burial of a living man.

A man's as miserable as he thinks he is.

No man was ever great without some portion of divine inspiration.

Until you have settled in your mind, what is best, you will be in a state of irresolution.
