From a poem in J. R. R. Tolkien's The Fellowship of the Ring.
The full quote is "All that is gold does not glitter, not all those who wander are lost; the old that is strong does not wither, deep roots are not reached by the frost. From the ashes a fire shall be woken, a light from the shadows shall spring; renewed shall be the blade that was broken, the crownless again shall be king."
Not All Who Wander are Lost sticker. Tolkein's great quote salutes those who dare to think'outside the box'. After all, the people who dream the biggest dreams are the ones who change our world in ways that really count.
