Leadership is a 3-dimensional challenge.  

The 3 Dimensions of Leadership 

1. Leaders have to control their emotions, make tough decisions and self-motivate. This is the personal dimension of leadership.
2. Leaders have to build relationships, influence behavior and develop others. This is the interpersonal dimension of leadership. 
3. Leaders have to create healthy environments, positive team dynamics and sustainable cultures. This is the group or team dimension of leadership. 

Why this is important - 

• Leaders tend to excel at and prefer different dimensions of leadership
• We spend more time in the dimension we prefer 
• Leadership is a perishable skill - we lose what we don't use
• It's easy to develop blind spots in dimensions we avoid
