If you disagree with your boss on monday, respectfully say why and then drop it. By tuesday or wednesday, you may be calling on them for backup when you need it most. Don't overlook the help a colleague can provide too. At the end of the workweek, your flexible outlook and willingness to adapt to changing circumstances make you a very valuable team member, and you'll even find time to return a favor. It all makes for excellent business karma. This weekend, you may rediscover an interest that offers a new next step on your career path.
