Our language has wisely sensed the two sides of being alone. It has created the word “loneliness” to express the pain of being alone. And it has created the word “solitude” to express the glory of being alone. – Paul Johannes Tillich, The Eternal Now

I think that I cannot preserve my health and spirits, unless I spend four hours a day at least — and it is commonly more than that — sauntering through the woods and over the hills and fields, absolutely free from all worldly engagements. – Henry David Thoreau
