According to Larry Wall, original author of Perl, there are three virtues of a programmer:

1. Laziness: Automate things so you don't have to do it over and over again. Document what you wrote so you don't have to answer so many questions about it.
2. 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.
3. Hubris: The quality that makes you write (and maintain) programs that other people won't want to say bad things about.
