Understand, analyze, and develop all of your players' individual strengths. Don't try to change people. Instead, work to improve them. When there's no margin for error, be a perfectionist. Demand continued improvement from your players.
Every kick counts.
Pace your players. Don't have them kick so many balls early in the season that their legs wear out. Technical and mental competencies build on each other. Develop chemistry with each of your players. Believing that you can be the best, and sacrificing to be the best, will motivate your players by example.
