On my office desk sits a jar filled with rocks, none of which are rare or have any monetary value. Whenever my wife and I travel, we find a pocket-sized rock, tote it back home, and add it to our stockpile. For us, these random bits of earth represent life outside of work and remind us of our journeys together. I wholeheartedly encourage you to start your own worthless collection of priceless memories.
