Seneca

No one can lose either the past or the future; how could anyone be deprived of what he does not possess?

A good character, which is formed by a good life, is the greatest gift of all.

While we are postponing, life speeds by.

No man is given a shorter amount of time than he is capable of using.

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

It is not that we have a short time to live, but that we waste a lot of it.

No person has been granted a shorter life than they can bear.

He who suffers before it is necessary, suffers more than is necessary.

He who is brave is free.

The life we receive is not short, but we make it short by wasting it.
