1.   Make up your mind to be happy. Learn to find pleasure in simple
      things.

2.   Make the best of your circumstances. No one has everything and
      everyone has something of sorrow mixed intermingled with
      gladness of life. The trick is to make the laughter outweigh the
      tears.

3.   Don't take yourself too seriously. Don't think that somehow you
      should be protected from the misfortunes that befall all of us.

4.   You can't please everybody. Don't let criticism worry you.

5.   Don't let your neighbor set your standards. Be who YOU are.

6.   Do the things you enjoy doing, but, stay out of debt.

7.   Never borrow trouble. Imaginary things are harder to bear than
      real ones.

8.   Since hate poisons the soul, do not cherish jealousy. Avoid
      people who make you unhappy.

9.   Have many interests. If you are unable to travel, read books
      about places you would like to see. Get lost in the voyage as
      though you were really there.

10. Don't hold postmortems. Don't spend your time brooding over
      sorrows or mistakes. Don't be one who never gets over things.

11. Do what you can for those less fortunate than yourself.

12. Keep busy at something. A busy person never has time to be
      unhappy.
