Quiet people have the loudest minds
English theoretical physicist, cosmologist, and author who was the director of research at the Centre for Theoretical Cosmology at the University of Cambridge at the time of his death.
Courtesy costs nothing, but buys everything
A man who dares to waste one hour of time has not discovered the value of life
Ask not what your country can do for you; ask what you can do for your country
Anyone who lives within their means suffers from a lack of imagination
Whosoever desires constant success must change his conduct with the times
I would prefer an intelligent hell to a stupid paradise
