So do good businesses. I have yet to see an outstanding business or football team without a good coach. Good coaches train others to assist them in becoming better at what they do. They don't try to do it alone. Good coaches recognize when they need help and are not afraid to ask for assistance.
Good coaches are mentors.
They know that everyone can learn from someone else. The more a business practices the basics, the better it will be able to meet the changing needs of the market. Soon, like the quarterback who becomes familiar with various defenses, a manager begins to view what used to be obstacles to growth as mere bumps on the road. If you are not a great coach don't despair. Make sure the All-Pro is there next to the rookie.
