There was a recent article that bubbled up HN that I can't find with life lessons from a wise old programmer that posted a new list every year.

One of the things that stood out to me from hist list went something like "discover the thrill of being extremely polite to people who are rude to you." Being no saint myself this really resonated with me.

I wouldn't walk out, and I certainly wouldn't take an offer, but I'd stay for the interview for the trill of behaving excellently.
