It's not what you look at that matters, it's what you see - i.e. compare it to, something worse or better, that determines whether you are respectively grateful and happy or ungrateful and bitter.
Henry David ThoreauWhite Pond and Walden are great crystals on the surface of the earth, Lakes of Light.... They are too pure to have a market value;they contain no muck. How much more beautiful than our lives, how much more transparent than our characters are they! We never learned meanness of them.
Henry David ThoreauA minority is powerless while it conforms to the majority; it is not even a minority then; but it is irresistible when it clogs by its whole weight.
Henry David ThoreauThe gentle rain which waters my beans and keeps me in the house today is not drear and melancholy, but good for me too. Though it prevents my hoeing them, it is of far more worth than my hoeing. If it should continue so long as to cause the seeds to rot in the ground and destroy the potatoes in the low lands, it would still be good for the grass on the uplands, and, being good for the grass, would be good for me, too.
Henry David ThoreauMost of the luxuries and many of the so-called comforts of life are not only not indispensable but positive hindrances to our progress. Our life is frittered away by detail. I say let your affairs be as two or three, not a hundred or a thousand. And keep your accounts on your thumb nail.
