The art of living does not consist in preserving and clinging to a particular mode of happiness, but in allowing happiness to change its form without being disappointed by the change; happiness, like a child, must be allowed to grow up. – Charles L. Morgan

For happiness one needs security, but joy can spring like a flower even from the cliffs of despair. – Anne Morrow Lindbergh

If the day and night be such that you greet them with joy, and life emits a fragrance like flowers and sweet-scented herbs, is more elastic, more immortal — that is your success. All nature is your congratulation, and you have cause momentarily to bless yourself. – Henry David Thoreau, Walden
