If you just got a point for never having written a postcard, go write a postcard! And mail it to someone that you appreciate in your life. It doesn’t need to be from anywhere exotic or say anything profound, it just takes a few sentences. If you really want to get fancy about it, a lot of little art galleries sell postcard sized prints and you can give someone a tiny little piece of art that speaks to you. Or go to a museum and buy like 10 at the gift shop and keep a stockpile to send when you want to reach out. People love it, and you probably will too.
