Stretch assignments aren't just for the office. Penelope Trunk from the Brazen Careerist has an interesting post about how your overall satisfaction with life is tied to how willing you to challenge yourself at home. If your routine is the same every night (fast food, 2 hours in front of the tv, and 3 hours surfing the internet aimlessly), how can you expect to be a challenge-taking go-getter at work? Mix up your routine just a little bit and you will be surprised at the results.
