No human pursuit achieves dignity unless it can be called work, and when you can experience a physical loneliness for the tools of your trade, you see that the other things - the experiments, the irrelevant vocations, the vanities you used to hold - were false to you.

I look at my yesterdays for months past, and find them as good a lot of yesterdays as anybody might want. I sit there in the firelight and see them all. The hours that made them were good, and so were the moments that made the hours. I have had responsibilities and work, dangers and pleasure, good friends, and a world without walls to live in.

I learned what every dreaming child needs to know, that no horizon is so far you cannot get above it or beyond it.

Africa is mystic; it is wild; it is a sweltering inferno; it is a photographer's paradise, a hunter's Valhalla, an escapist's Utopia. It is what you will, and it withstands all interpretations. It is the last vestige of a dead world or the cradle of a shiny new one. To a lot of people, as to myself, it is just 'home'. It is all these things but one thing - it is never dull.

Success breeds confidence.

Silence is never so impenetrable as when the whisper of steel on paper strives to pierce it.

Talk lives in a man’s head, but sometimes it is very lonely because in the heads of many men there is nothing to keep it company - and so talk goes out through the lips.
