For some people, perl is their life. For others, programming languages. For more others, computer science. For even more, it's some other profession. You get out of PM wat you take out of PM.

Personally, I spend enough time on PM a day so that the synapses fire to get me away from the drudgery of monkey work and to push my wisdom (not knowledge) furhter, particularly to answer design, ethical/moral and the open ended questions.
