As I was starting my academic career, it was almost considered to be a negative signal to your career to get involved in politics ... But to me that was a sign you were doing something useful.

There was very much a real feel that we probably pretty much discovered every major fossil field in Africa. And in fact, some scientists even wrote that down at the turn of the millennia. It wasn’t a great time to be proposing to explore and push new, because we hadn’t succeeded, theoretically, being given the chance. All the big discoveries were in old sites. ... I was still an extraordinary believer in that there was more out there to be discovered. I just wasn’t demonstrating.

The strategy we've adopted precludes our following standard diversification dogma. Many pundits would therefore say the strategy must be riskier than that employed by more conventional investors. We disagree. We believe that a policy of portfolio concentration may well decrease risk if it raises, as it should, both the intensity with which an investor thinks about a business and the comfort-level he must feel with its economic characteristics before buying into it.

I went to the opera practically every night. I went to something practically every night, just learning and seeing and absorbing, and what I noticed is that there were singers that were only sort of slightly older than I whose voices sounded as though they were many decades older than that, and didn’t sound pretty, and I needed to understand what was happening. I mean there were singers that were 28 or 30 years old or something, and I would speak to them afterwards to say, “Was your voice tired tonight? Tell me what’s happening,” because I didn’t understand it. Their voices should have sounded fresh and blooming and wonderful, but instead they sounded different, and it was because they were singing a different opera every night, and singing whatever was offered, and I didn’t understand and needed to understand — because no one was telling me these things — why they just didn’t say no. Why didn’t they just say, “Oh no, I don’t think I should.”
