A Recipe for Happiness (author unknown) is neither Victorian nor 1970's, but the following is appropriate for all people, of all eras.
1 large sense of humor
1 warm, wide smile
1 generous handful patience
Dash of courtesy
Plenty of love and humility (you can never add too much).
Mix all ingredients together and press through a sieve to strain out lingering amounts of unkindness. Yield: Serves all of mankind.
