I never let practical considerations clutter my youthful dreams.

I was born to be an explorer. There never was any decision to make. I coudn't be anything else and be happy,the desire to see new places, to discover new facts- the curiosity of life always has been a resistless driving force to me.

Always there has been an adventure just around the corner--and the world is still full of corners.

Man is an ape with possibilities.

Palaeontology is the Aladdin's lamp of the most deserted and lifeless regions of the earth it touches the rocks and there spring forth in orderly succession the monarchs of the past and the ancient river streams and savannahs wherein they flourished. The rocks usually hide their story in the most difficult and inaccessible places.

I wanted to go everywhere. I would have started on a day's notice for the North Pole or the South, to the jungle or the desert. It made not the slightest difference to me.
