There is nothing more despicable than an old man who has no other proof than his age to offer of his having lived long in the world.
Other Seneca the Younger quotes:
One of the most beautiful qualities of true friendship is to understand and to be understood.
A friend always loves, but he who loves is not always a friend.
Associate with people who are likely to improve you.
If you wish to be loved, love.
A coward calls himself cautious, a miser thrifty.
Our care should not be to have lived long as to have lived enough.
Life is long, if you know how to use it.
No possession is gratifying without a companion.
Sometimes even to live is an act of courage.
Know thyself; this is the great object.
