It seems fitting here to add a few quotes of Henry David Thoreau, a writer who believed in simple life surrounded by nature.
I went to the woods because I wished to live deliberately, to front only the essential facts of life, and see if I could not learn what it had to teach, and not, when I came to die, discover that I had not lived.Henry David Thoreau
I have learned, that if one advances confidently in the direction of his dreams, and endeavors to live the life he has imagined, he will meet with a success unexpected in common hours.Henry David Thoreau
Every creature is better alive than dead, men and moose and pine trees, and he who understands it aright will rather preserve its life than destroy it.Henry David Thoreau
And, because it matters to me:
Until he extends the circle of compassion to all living things, man will not himself find peace.Albert Schweitzer
