Don't play tennis or any other sport that requires a change of clothes. Mountain climbing is OK, though, and real programmers often wear climbing boots to work in case a mountain should suddenly spring up in the middle of the machine room. Don't like the team programming concept. Unless, of course, they are the Chief Programmer. Have no use for managers.
Managers are a necessary evil.
They are for dealing with personnel bozos, bean counters, senior planners, and other mental defectives. Don't drive around in clapped out mavericks. They prefer BMW's, Lincolns, or pick-up trucks with floor shifts. Fast motorcycles are highly regarded. Like vending machine popcorn.
