The next time you go to your team meeting, take a few moments to observe the team functions and roles. At any particular moment, someone is leading, taking notes, keeping on track and on time, as well as participating in the meeting. Watch closely who is performing each function.
The team leader may be working very hard at all of these functions — not only leading the meeting, but keeping notes on a yellow legal pad, steering the agenda and the timetable, and answering questions without a whole lot of participation.
If that leader is you, well then my friend, you are working too hard!
