The last time I looked I hadn't seen anyone carrying around a magic wand. People do not create star performers; star performers emerge from the challenges and insights they gather from experiences.
Mentoring others is all about having the right conversations to create actionable events. My coaching is all about asking the right questions to move employees from their current state to a future state of being a leader. Leaders come in all sizes, some of the most influential people I know had very little status in their organization.
People have the free will to engage with me or not. Making a choice is an action. Sending a person to coaching, a course , giving them a book to read on a topic can be a huge waste of time. Think of someone that repeats the same behavior over and over again that you hoped the workshop would cause the person to be enlightened and how they continued to behave in the same manner.
