One of the biggest calls as a leader is to strengthen others. The greatest leaders this world has seen had the ability to find untapped potential in people and then empower them to make great things. If you want to succeed as a leader, you must accept the grant rule in your life.
You see, if you do not support people you are not raising people to be independent. Now, you might think that if you are creating independent people, you are creating people who can oppose your own leadership. However, the opposite is usually the opposite. If you treat people with respect and strengthen them to make great things, they will honor and respect you for it.
People do not want to be held down. They will be released to do the great role they think they will do in their lives. If you keep people from reaching their potential in life, they will come to despise you personally and as a leader. People want to succeed in life as much as you do.
Promoting people to succeed will create an amazing group of people around you who will be able to do all that is thrown on them. The facts of the case are, if you do not strengthen people and help them achieve their full potential, then you do not really underestimate your own potential as a leader. If you strengthen people you are also strengthening yourself.
