Good manners.
Doing to others as you would have done to yourself;
Love your neighbour as yourself.
Be considerate.
Humility is when you go to a party and instead of sitting at the high table, you choose to sit where the ordinary guests would have sat.
Humility is when you do not force yourself to fit in with the rest.
Humility is when you acknowledge your limitations.
Drop that know-it-all attitude, will you?
Accept correction instead.
