Seek to work with a great team. If you are responsible to a team, make sure they are quality people, conscious of the effective use of time. A productive team is gold. There may not be much you can do directly to affect who is on the team, but to the degree you do have influence, exercise it.
Quality team members want you doing the most important thing at any given point in time. By your very position, you are in place to advance the purposes of the organization. These men and women want you operating at peak efficiency.
