John Steinbeck said this quote

What good is the warmth of summer, without the cold of winter to give it sweetness.

~ John Steinbeck

It has always seemed strange to me...The things we admire in men, kindness and generosity, openness, honesty, understanding and feeling, are the concomitants of failure in our system. And those traits we detest, sharpness, greed, acquisitiveness, meanness, egotism and self-interest, are the traits of success. And while men admire the quality of the first they love the produce of the second.

~ John Steinbeck

Power does not corrupt. Fear corrupts... perhaps the fear of a loss of power.

~ John Steinbeck

Tom felt his darkness. His father was beautiful and clever, his mother was short and mathematically sure. Each of his brothers and sisters had looks or gifts or fortune. Tom loved all of them passionately, but he felt heavy and earth-bound. He climbed ecstatic mountains and floundered in the rocky darkness between the peaks. He had spurts of bravery but they were bracketed in battens of cowardice.

~ John Steinbeck
