To be a good loser is to learn how to win.
Only the educated are free.
Know or listen to those who know.
By failing to prepare, you are preparing to fail.
You can have a lot of unhappiness by not having money, but the reverse is no guarantee of happiness.
To me, thoughts are fun and art is fun. The strength of our society should not be idle entertainments but the joy of pursuing ideas.
