• I've always felt that maybe one of the reasons that I did well as a student and made such good grades was because I lacked confidence. Lacked self-confidence, and I never felt that I was prepared to take an examination, and I had to study a little bit extra. So that sort of lack of confidence helped me, I think, to make a good record when I was a student.
