As a coach, you're just trying to figure out how to keep a team on edge. You've got to find that edge.
Have character, don't be one.
Study people who can teach you how to deal with people.
Go from good to great because good is the enemy of great.
Only run special plays for special players; find plays that fit your players.
If you have to 'try hard' to 'try hard, you are already beaten.
