Extreme hopes are born from extreme misery. - Bertrand Russell

"The secret of happiness is to face the fact that the world is horrible, horrible, horrible."

"It is essential to happiness that our way of living should spring from our own deep impulses and not from the accidental tastes and desires of those who happen to be our neighbors, or even our relations."

"To like many people spontaneously and without effort is perhaps the greatest of all sources of personal happiness."

"Never let yourself be diverted, either by what you wish to believe, or what you think could have beneficent social effects if it were believed; but look only and solely at what are the facts."

"It is not what the man of science believes that distinguishes him, but how and why he believes it. His beliefs are tentative, not dogmatic; they are based on evidence, not on authority or intuition."
