I have found it advisable not to give too much heed to what people say when I am trying to accomplish something of consequence. Invariably they proclaim it cant be done. I deem that the very best time to make the effort. – Calvin Coolidge
If I had permitted my failures, or what seemed to me at the time a lack of success, to discourage me I cannot see any way in which I would ever have made progress. – Calvin Coolidge
