Have no friends not equal to yourself.
To go beyond is as wrong as to fall short.
When you have faults, do not fear to abandon them.
Better a diamond with a flaw than a pebble without.
Hold faithfulness and sincerity as first principles.
Do not impose on others what you yourself do not desire.
To see what is right and not to do it, is want of courage.
It is only the wisest and the stupidest that cannot change.
What you do not want done to yourself, do not do to others.
They must often change who would be constant in happiness or wisdom.
