When you're involved in guiding the careers of others, it's easy to overlook the need to monitor and direct the course of your own. This can be a costly oversight — for you as well as for your company. You made it to the head of your work team, and now you're caught up in the day-to-day functions of managing. But you have to remember how to get your hands dirty. That's what got you this far, and that's what is going to keep you valuable to the company. When you let your primary job skills erode, you limit your options and your opportunities.
