Trust resides squarely between faith and doubt.

This duality, making yourself better while teaching and developing others' judgment capabilities, is the key to leadership that is both productive and principled.

Just as no great painting has ever been created by a committee, no great vision has ever emerged from the herd.

Effective leaders make a full commitment to be a learner, to keep increasing and nourishing their knowledge and wisdom.

Great leaders love talent and know where to find it. They surround themselves with talented people who can work effectively together.

People vary enormously in how they learn. Some learn through their eyes - by reading but also by responding to all kinds of visual information. Others learn mostly through their ears or touch or other senses.

One of the qualities that all the leaders have is a voracious appetite to learn whatever they do not as yet know and understand, coupled with an openness to new experiences.
