“Both optimists and pessimists contribute to society. The optimist invents the aeroplane, the pessimist the parachute.”
“Live and invent. I have tried. I must have tried. Invent. It is not the word. Neither is to live. No matter. I have tried. [...] I say living without knowing what it is. I tried to live without knowing what I was trying. Perhaps I have lived afterall, without knowing.”
“I find out what the world needs. Then I go ahead and try to invent it”
“The the question whether I am a pessimist or an optimist, I answer that my knowledge is pessimistic, but my willing and hope are optimistic.”
“I think play must have been invented so we wouldn't go mad thinking about certain things.”
