From the book Minute Motivators for Leaders, by Stan Toler:
'You can always spot an A-level leader. How? He or she will have A-level subordinates. Those who follow them will have some of their skills, some of their determination, and some of their vision. True leadership is contagious. People catch it, and it germinates in their spirits.
You can spot B-level leaders just as easily. They'll probably have C-level subordinates. B-level leaders are intimidated by the potential of others. They are keepers of the keys who prevent the unlocking of someone's potential.
A-level leaders are not threatened by great potential. In fact, they look for it, seek it, recruit it, and develop it. It thrills them. It drives them on to even greater accomplishments. They have discovered the secret of excellence. They have realized the great possibility - that they can multiply their work by developing and training their associates to reach their full capability.
A great leader will not be a leader of followers. He or she will be a leader of leaders.'
Leaders grow leaders.
