You can't please everybody. Don't let criticism worry you. Don't let your neighbour set your standards. Do the things you enjoy doing, but stay out of debt. Don't borrow trouble.
Imaginary burdens are harder to bear than the actual ones.
Since hate poisons the soul, do not cherish enmities or grudges. Avoid people who make you unhappy. Have many interests. If you can't travel, read about new places. Don't hold postmortems.
