Seneca

Nature has given to us the seeds of knowledge, not knowledge itself.

We should every night call ourselves to an account; What infirmity have I mastered today? What passions opposed? What temptation resisted? What virtue acquired? Our vices will abort of themselves if they be brought every day to the shrift.

Other men's sins are before our eyes; our own are behind our backs.

Most powerful is he who has himself in his own power.

The person you are matters more than the place to which you go.

While we are postponing, life speeds by.

There is a noble manner of being poor and who does not know it will never be rich.

Not he who has little, but he whose wishes more, is poor.

This life is only a prelude to eternity.

It is the quality rather than the quantity that matters.
