You are a leader when people choose to follow you

You are a leader when people choose to follow you: because you stand for something bigger, because you’re taking them somewhere compelling, because you’re helping them become more of who and what they already are, because they see in you an embodiment of something they’d like to be. Leadership happens in the space between you and someone else. You can be a leader in some areas but not in others: context counts.
