Don’t Surround Yourself with Smarter People

Out of necessity, I've pretty much always worked with people smarter than I am. ;-)

Intelligence is a multiple axis sort of thing, not a single number. A smart developer benefits from working with the people who are smarter on other axis of intelligence such as business or design.

This not to say that someone can't be attractive, athletic, have great common sense, be artistic and also a math wiz. It's is just not common to be strong on all axis.
