“What do you think of the human race?” asks a friend who has just graduated in sociology.
“I think it’s strange – so alike and yet so different! We are capable
 of working together, of building the Pyramids of Egypt, the Great Wall 
of China, the cathedrals of Europe and the temples of Peru. We can 
compose unforgettable music, work in hospitals, create new computer 
programs.
“But at some moment all this loses its meaning, and we feel alone, as
 if we were part of another world, different from the one we have helped
 to build.”
“At times, when others need our help, we grow desperate because this 
prevents us from enjoying life. At other times, when nobody needs us, we
 feel useless.
“But that’s the way we are. We are complex human beings. Why despair?”
“We are what we think. All that we are comes from our thoughts. 
Through thought we construct and destroy the world. Thought follows us 
like a cart follows the pair of oxen. We are what we think. Your 
imagination can cause you more harm than your worst enemy. But once you 
control your thoughts, no one can help you as much as they can – not 
even your father or mother.”
