Know when to advance and when to retreat. Be an active listener. Encourage and reward risk-taking in others. Be a mentor to someone on the way up. Invest time in training your staff.
Nothing pays off more.
Celebrate the personal and professional triumphs of your staff. Unless you swim in the meet yourself, accomplishments belong to the team, not the coach. Look at every problem as an opportunity. Cut down on paper. Do more face to face communication.
