Be sure to take more photos and record more memories. Really, you'll find that many things are forgotten completely after a couple of days, and you might not even remember what you did on your happiest day last week. Only when you look back at the photos from that time can you recall those moments. Each event, each memory—photos and written records—can make you feel as if you're reliving that day. Photos and words both carry warmth; the photos you unintentionally took at a certain stage, the words you wrote, your feelings at the time, your environment, and your mood—all are stored within those photos and words. When you see familiar scenes or texts again in the future, it will pull your thoughts back to a long time ago, recreating the scene at that moment, even though you can never go back.
