If you are the lead wolf at the top and carry great responsibility, for example for a big business unit, a big country, or even an entire company, then you have to lead well to be successful. You have to endure loneliness, because you decide more and more alone, often with fewer people around you than in previous roles.
As the lead wolf, you often get less feedback, and that feedback may be less honest, because more and more people in the hierarchy are on a level below you, and may be afraid of your position, or of you as person or both. You may find you receive filtered feedback out of fear or convenience. To address this missing or filtered feedback, ask questions and listen, especially to less comfortable answers.
