I believe I am the luckiest person I know. I have reached the age of 72 without having a serious illness or injury. I have never been poor or in debt. I have always been treated with respect -- deference, even -- tho I am deviant (not to mention vile) in a dozen ways.

There is, however, a trait of character (which luck is not), which I call felicific efficiency, or felicificity: output of happiness per unit input of luck. On that scale I rank very low indeed.
