Study nature, love nature, stay close to nature. It will never fail you.
Frank Lloyd Wright

If a man walks in the woods for love of them half of each day, he is in danger of being regarded as a loafer. But if he spends his days as a speculator, shearing off those woods and making the earth bald before her time, he is deemed an industrious and enterprising citizen.
Henry David Thoreau

Nature has no mercy at all. Nature says, "I'm going to snow. If you have on a bikini and no snowshoes, that's tough. I am going to snow anyway."
Maya Angelou
