A short, finished list rather than an endless feed: 70 of the best anniversary quotes ever written, picked out of the full anniversary archive on QuoteForever. You will find Mo Farah, Dave Willis, Oscar Wilde and Anne Morrow Lindbergh among them.
Read the list top to bottom, or use it as a starting point - every author name links to everything else they said, and every quote has its own page you can share or turn into an image.
