Remember being the leader means that you have been placed in a position to serve others; it has nothing to do with you; leaders are accountable for the success and livelihoods of dozens, hundreds, or thousands of people. They should never forget this fact and never act in a cavalier fashion. Their decisions, actions, and how they carry themselves impact a large and diverse community.
Leaders should focus on serving their teams first because real leaders forget about themselves and instinctively react in their team's best interest.
When a great leader allows you to spread your wings and soar to your full potential. Believe me, you will fly back to that leader with gratitude thanking them for seeing the potential you knew you had and allowed you to unleash so it could take you to places you only ever dreamed of. That is the power of a true leader. That is a leader for the people.
