Scott Adams did a piece on the role of luck for making a good life. It seemed as if he were implying that being born with darker skin than his was one item on his "bad luck" list.
I am not convinced of the latter, but most of "good luck" involves genetics in every sense, from appearance to IQ to illnesses to character traits and talents. A non-dysfunctional family and a decent middle-class upbringing are pretty good lucks too.
Do you view life as a series of opportunities knocking, or as a series of back lucks? I do the former.
Like many Americans, I probably could have taken my career further but, at a point, I was content. I enjoy viewing the Matterhorn, but feel no urge to climb it other than the normal macho impulse. I am glad that others do.
