This was the first post I ever read by Patrick. It and Joel Spolsky's blog should be regarded as compulsory reading for all CS grads. Definitely set me on the right path.
I think a good follow up of "don't call yourself a programmer" is "Don't look for a job". The moment you start looking for a job, you're pretty much that "Java programmer" again. Somehow, the people I meet who can't find a job are those who are looking, while those who speak about their employment in literally any other way than "looking for a job" never seem to have a problem. I don't know exactly which way the causation link works (maybe people who are good at getting jobs are privileged enough to not have to think about it in that way), but I'm pretty sure that the word 'job' and mental model associated with it is not optimal.
