Great teammates understand that they need the team, the team does not need them. They know that their individual effort cannot scale past what their participation on the team can accomplish. They know that they are replaceable and therefore expendable. Ordinary teammates get this the wrong way around. They tend to centralize everything around themselves, thinking, “What would happen if I didn’t show up?” Well, the answer is that someone else will eventually do the job, hopefully better then their predecessor, with the collective team effort and commitment to learning that is necessary.
