There are things that I really am interested in doing that I can't do if I continue to do what I'm doing. And I - teaching would be a big thing for me. I'm an adjunct instructor at Johns Hopkins and teach business communications and ethics, so very different from what I do on a daily basis.

I go in every day to the office. I don't accomplish hardly anything. I mean, in terms of – it just takes me way longer to do things. And Greg is so good. It was kind of embarrassing how good he is, because he has covered – you know, we've got about 200 businesses within Berkshire, you know, that came about, and I can't name the manager's names or their wives names, or – and I haven't seen them, you know, in a long time.

But I continued to think that illness happened to patients and not to doctors, even though I was now retired. Twenty months after I had my brain scanned, I was diagnosed with advanced prostate cancer. I had had typical symptoms for years, steadily getting worse, but it took me a long time before I could bring myself to ask for help. I thought I was being stoical when in reality I was being a coward.

In 1990 I retired from my firm, I.M. Pei & Partners, and for two years I didn't do much. Then I started to get kind of antsy, so I decided, I'm going to do some more work. And I chose to do work outside the U.S. because I've spent 45 years here and I wanted to learn more about what's happening in the rest of the world.

Being respected, because I have to deal with this each and every day of my life. Each and every day of my life, when I go to a public place, someone might recognize me, or might not, that doesn’t make or break my day. The thing that I walk in expecting is that, whether they recognize me or not, I’m going to be treated with respect.

There are three teachers who are still involved in my life. Ray Wilson — who is my office manager, and who was a teacher in my high school, as well as my basketball coach in high school — is very much involved in my life, and is a real father figure for me. A gentleman named Earl Mosley, who never specifically taught me, but was always there, and was a role model for me, was a coach when I was a freshman. And then a guy named Charles McIlwaine, who is a teacher and a coach. In my high school years those three really stood out, really helped to become part of the support group that’s necessary when you’re experiencing all types of physical changes and mental changes, to help to explain things, and put them in the proper perspective.
