The trick is to make the laughter outweigh the tears. Don't take yourself too seriously. Don't let your neighbor set your standards. Do the things you enjoy doing, but stay out of debt. Don't borrow trouble.
Imaginary things are harder to bear than the actual ones.
Since hate poisons the soul, do not cherish enmities and grudges. Don't hold post-mortems. Don't spend your life brooding over sorrows and mistakes. Don't be one who never gets over things. Do what you can for those less fortunate than yourself.
