1) Stretch your mind, reach beyond your preconceptions; learn to think of things in ways you have never thought before.

2)
Acquire tools with which to critically examine and evaluate new ideas, including your own cherished ones.

3)
Settle eventually on a framework or set of frameworks that organize what you know and believe and that guide your life as an individual and a leader.

2) But never get so comfortable as to believe that your frameworks are the final word, recognizing the strong psychological tendencies that favor sticking to your worldview. Learn to keep stretching your mind, keep stepping outside your comfort zone, keep venturing beyond the familiar, keep trying to put yourself in the shoes of others whose frameworks or cultures are alien to you, and have an open mind to different ways of parsing the world. Before you critique a new idea, or another culture, master it to the point at which its proponents or members recognize that you get it.
