Don't take yourself too seriously. Don't let criticism worry you - you can't please everybody. Don't let your neighbors set your standards - be yourself. Do things you enjoy doing but stay out of debt. Don't borrow trouble.
Imaginary things are harder to bear than actual ones.
Since hate poisons the soul, don't cherish enmities and grudges. Avoid people who make you unhappy. Have many interests. If you can't travel, read about places. Don't hold post-mortems or spend time brooding over sorrows and mistakes.
