When asked by a young man if he should seek to marry, Socrates answered him:

“By all means marry: if you get a good wife, you will be happy; if you get a bad one, you will become a philosopher.”

The Oracle of Delphi called Socrates 'the wisest man' because he said:

"I know I know nothing!"

Of course, he only knew this because his wife, Xanthippe, told him so.

Every day!
