Yesterday I ran into a group picture with Renzo Piano. Nothing glamorous or professional, simply a group picture. Something about him gave me the impression of a very approachable down-to-earth person.
On that note, I have to say that those talented and intelligent people, who are aware of their abilities, are easier to work with when they are not contemptuous to others. As a professional coach would write, one must take care not to be a victim of their 0wn success. I'm sure the ones around the intelligent and talented appreciate that.
