Locksmiths, if you have one or more employee, by default, you should be a teacher. You also should be either a leader or a manager. If you have a locksmith who is learning the trade, you should be both.
Leaders, according to Inc.com, have a unique ability to rally employees around a vision. Whereas managers are more adept at executing the vision in a very systemic way and directing employees on how to do so.
Because their belief in the vision is so strong, employees will naturally want to follow Leaders. Leaders also tend to be willing to take risks in pursuit of the vision.
Managers see all of the intricate moving parts and understand how to make them harmonize. Managers are usually very risk-adverse.
