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.

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.

I think it's … the profession is starting to realise that in part it's the general climate, and the way we treat each other is not conducive for having more women in the profession. It's not just about promotion but it's about the general environment and how people talk to each other and address each other in seminars and things like that, that we need to work on a culture that is more respectful and that will be more acceptable for many women who think that they don't want to play the games of shouting at each other.

I do not think much of the accident or good luck theory of self-made men. It is worth but little attention and has no practical value. An apple carelessly flung into a crowd may hit one person, or it may hit another, or it may hit nobody. The probabilities are precisely the same in this accident theory of self-made men. It divorces a man from his own achievements, contemplates him as a being of chance and leaves him without will, motive, ambition and aspiration. Yet the accident theory is among the most popular theories of individual success.
