The Team Member Handbook
One of the most basic elements of teamwork is this:
Be good at what you do.
Teams need talent. The more of it you bring to the group, the more you can contribute. Build your skills, and, in a very real sense, you are building the team.
You can't have a high-powered team with low-talent people. And sometimes the weakest link in the chain sets the limit on what the group as a whole can achieve.
So keep stretching. Polish your skills and perfect your moves. Master the fundamentals of your job.
