“How beautifully leaves grow old. How full of light and color are their last days.”

“The universe is so unhuman, that is, it goes its way with so little thought of man. He is but an incident, not an end. We must adjust our notions to the discovery that things are not shaped to him, but that he is shaped to them. The air was not made for his lungs, but he has lungs because there is air; the light was not created for his eye, but he has eyes because there is light. All the forces of nature are going their own way; man avails himself of them, or catches a ride as best he can. If he keeps his seat, he prospers; if he misses his hold and falls, he is crushed.”

“I still find each day too short for all the thoughts I want to think, all the walks I want to take, all the books I want to read, and all the friends I want to see.”

I have climbed its mountains, roamed its forests, sailed its waters, crossed its deserts, felt the sting of its frosts, the oppression of its heats, the drench of its rains, the fury of its winds, and always have beauty and joy waited upon my goings and comings.”

“You can get discouraged many times, but you are not a failure until you begin to blame somebody else and stop trying.”

“Look underfoot. You are always nearer to the true sources of your power than you think. The lure of the distant and the difficult is deceptive. The great opportunity is where you are. Don't despise your own place and hour. Every place is the center of the world.”

“If I were to name the three most precious resources of life, I should say books, friends, and nature....”
