In my personal experience I have hardly come to know the wretchedness of mankind better than as a result of the general theory of relativity and everything connected to it. But it doesn't bother me.

Ever since childhood I have scorned the commonplace limits so often set upon human ambition. Possessions, outward success, publicity, luxury - to me these have always been contemptible. I believe that a simple and unassuming manner of life is best for everyone; best both for the body and the mind

Where you see difficulty, I see opportunity.

I am also convinced that one gains the purest joy from spirited things only when they are not tied in with earning one's livelihood.

The environment is everything that isn't me.

Science is the process of making obviously erroneous ideas less obviously erroneous.

Concern for man and his fate must always form the chief interest of all technical endeavors. Never forget this in the midst of your diagrams and equations.
