Seneca

To be happy you must eliminate two things: the fear of a bad future and the memory of a bad past.

We suffer more often in imagination than in reality.

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

The good in life does not depend upon life’s length, but upon the use we make of it.

It is best to endure what you cannot change.

It is not that we have a short time to live, but that we waste a lot of it. Life is long if you know how to use it.
