Nothing has advanced my skill and career more than being around programmers who are much better than I am at programming. There's something awe-inspiring when you first meet people who are better at coding than you. They are like wizards, commanding all of nature to bend to their will. In an hour, they sling out code it would take you weeks to get finished. Maybe you've gotten a chance to work with these masters of computation and hoped that some of their skills would rub off on you.
