We must leave our mark on life while we have it in our power.

There are things which cannot be carried through even with the good will of everybody concerned

One must in this lower world love many things to know finally what one loves the best.

I do not see eye to eye with the camera.

Now, looking back on my life in Africa, I feel that it might altogether be described as the existence of a person who had come from a rushed and noisy world, into a still country.

It is a sad hardship and slavery to people who live in towns, that in their movements they know of one dimension only; they walk along the line as if they were led on a string. The transition from the line to the plane into the two dimensions, when you wander across a field or through a wood, is a splendid liberation to the slaves, like the French Revolution. But in the air you are taken into the full freedom of the three dimensions; after long ages of exile and dreams the homesick heart throws itself into the arms of space.

It is not the visions but the activity which makes you happy, and the joy and glory of the flier is the flight itself.
