I love training. It's not just about the competing. I had an amount of natural talent – you need that to go so far – but, actually, what I had, I think, is an ability to make myself work hard, to do the things I didn't like doing, to do the things that I wasn't so good at.

I was very, very thorough, making sure I really understood how that telescope worked, and that it was working properly. I was quite convinced that I wasn't clever enough to be in Cambridge and would be thrown out at some stage. My policy was to work as hard as I could so that I'd know I'd done my best. We now label this as impostor syndrome, but we didn't recognise, and certainly didn't name it, back then.

I need to know what my editing voice is

That is true. That one little corner of South Africa, Port Elizabeth and its immediate surroundings, is a region that I know like the back of the hand that holds my pen as I write about it. I can stand on a street corner in Port Elizabeth, look at anybody and put together some sort of biography. I know where they come from, where they’re going. I have a feel of the textures of their life. If I stand on a street corner in New Haven, which is a place I’ve gotten to know as well as any place outside of South Africa, I am still at a total loss to identify the people passing me on that street.

They had large resources of compulsion at their disposal, but I was stubborn. Where my reason, imagination or interest were not engaged, I would not or I could not learn. In all the twelve years I was at school no one ever succeeded in making me write a Latin verse or learn any Greek except the alphabet. I do not at all excuse myself for this foolish neglect of opportunities procured at so much expense by my parents and brought so forcibly to my attention by my Preceptors.

My mother made the same brilliant impression upon my childhood's eye. She shone for me like the Evening Star. I loved her dearly—but at a distance. My nurse was my confidante. Mrs. Everest it was who looked after me and tended all my wants. It was to her I poured out my many troubles, both now and in my schooldays.

At the end he asked me if I would like to go into the Army. I thought it would be splendid to command an Army, so I said 'Yes' at once: and immediately I was taken at my word. ... I was told later that he had only come to the conclusion that I was not clever enough to go to the Bar. However that may be, the toy soldiers turned the current of my life.

First of all, you can correct mistakes much more easily. One sweep of the palette-knife 'lifts' the blood and tears of a morning from the canvas and enables a fresh start to be made; indeed the canvas is all the better for past impressions.

The cultivation of a hobby and new forms of interest is therefore a policy of first importance to a public man. But this is not a business that can be undertaken in a day or swiftly improvised by a mere command of the will. The growth of alternative mental interests is a long process. The seeds must be carefully chosen; they must fall on good ground; they must be sedulously tended, if the vivifying fruits are to be at hand when needed. To be really happy and really safe, one ought to have at least two or three hobbies, and they must all be real.

When I think of the fate of poor old women, so many of whom have no one to look after them and nothing to live on at the end of their lives, I am glad to have had a hand in all that structure of pensions and insurance which no other country can rival and which is especially a help to them.
