For upward of ten years I was a management consultant doing sleep and alertness consulting -- designing biocompatible shift schedules for 24-7 companies and teaching folks how to be healthy on night shifts. I eventually left the job due to excess travel, started my own company doing something similar, and that died a slow and painful death due to not enough sustainable money for marketing. The side effects of this were a portion of the reason I took a sabbatical from the boards this last year. Failing business = unhappy camper.
Gleefully, however, I just got hired to design games for Nintendo products (the DS, GBA and Revolution/Wii.) My employer has the Pixar license, so I'll be working on games for the new Pixar movies. Fun co-workers, creative work, no travel or dress code -- I could learn to like this.
