In college I had a very good friend. I met him in my portuguese class. He is one of the most brilliant people I know. He a PHD nd a Masters Degree in Engineering/Law by the the time he was 24.

One of the things I admired the most about him was the way he could relate to different groups of people. He could hold a very technical conversation with my sister (also an engineer) and 2 seconds later have a great conversation about art or music with someone else. We all knew he was brilliant, yet we never felt "dumb" when talking to him.

I think this is a great skill to develop
