(I finally tracked this down to the glossary of the Camel book, but I'd swear I've seen it in slightly different form elsewhere.) The Camel book mentions these three qualities:

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 that 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. [Also, the thing that makes you write programs to do something that's already been done, because you believe you can do it better --- Wim.] Hence, the third great virtue of a programmer.
