I am not optimistic or pessimistic. I feel that optimism and pessimism are very unbalanced. I am a very hard engineer. I am a mechanic. I am a sailor. I am an air pilot. I don't tell people I can get you across the ocean with my ship unless I know what I'm talking about.
R. Buckminster Fuller, Only Integrity Is Going to Count: Integrity Day, Los Angeles February 26, 1983
