Seneca

No man is free who is a slave to the flesh.

The only thing that is truly ours is time.

Hang on to your youthful enthusiasms — you’ll be able to use them better when you’re older.

There is no enjoying the possession of anything if you do not share it.

He who is not bold enough to be a fool is not a genius.

It is a man's mind which makes him happy or unhappy.

No man can be happy who does not consider himself one of the happiest of men.

A good mind does not change its purpose.

No man has ever become great without some divine inspiration.
