At my most pessimistic moments, I think that just knowing who Donald Knuth and Larry Wall are is strongly correlated with being above-average.

Well, laziness in terms of typing more, probably. Laziness in terms of thinking less, definitively no.

LAZINESS: The quality that makes you go to great effort to reduce overall energy expenditure. It makes you write labor-saving programs that other people will find useful, and document what you wrote so you don't have to answer so many questions about it. Hence, the first great virtue of a programmer.

IMPATIENCE: The anger you feel when the computer is being lazy. This makes you write programs that don't just react to your needs, but actually anticipate them. Or at least pretend to. Hence, the second great virtue of a programmer.

HUBRIS: Excessive pride, the sort of thing Zeus zaps you for. Also the quality that makes you write (and maintain) programs that other people won't want to say bad things about. Hence, the third great virtue of a programmer.

Of course, anyway I meant to point out "hubris" (as a response to singling out "narcissism" as a flaw) :)
