Take a trip to the Bahamas and put your toes in the sand. Go explore the Ancient Mayan Ruins. Take a tour through African jungles or see Paris from the top of the Eiffel Tower. Whatever calls to your inner explorer, go explore it! THEN, journal it!
Concert tickets, destinations along the way, a small map of the area, or a preserved plant. Keep track of it in a journal and on "down days" relive that experience. Remind yourself that there are many, many more adventures to be had. Go have them! Do not let anything ruin your happiness, and do not let anyone forget what makes you happy!
