A leader without any followers is just a guy taking a walk. That statement might be called a thinker but have you ever met someone who is a self-declared leader only to find that they are still looking for followers. Leadership is earned. It cannot be decreed by others, declared by one’s self, or determined by our DNA.
We become a leader when we inspire others to embrace a common goal. Followers must perceive a benefit to them or their cause before they will embrace the leadership that will get them to their cause.
