Hello! This seems like a really nice thread! I'm just going to write this in no particular order because all of these make me happy in their own way.

1. After a long day, getting to sit down and watch anime/BTS content (mainly Run episodes) before going to bed.
2. Hearing a song on one of my old playlists and realizing how much I liked that song. It gives me some nostalgia.
3. When it rains! It rains about once a month (or every two months, lol) where I live and I honestly just love the rain. Bonus if the sun comes out afterwards. I also love how everything smells afterwards.
4. Waking up and realizing I have nothing to do. It's one of the most satisfying things in my life, lmao. Also, waking up and feeling refreshed and taking afternoon naps.
5. Finding a nice book/manga and reading it in one sitting. I haven't really found a book that interests me lately though.
6. Just sitting and doing nothing. I like looking at the scenery and getting lost in thought.
7. Long car rides (as long as I'm not the one driving). I like cracking open the window and feeling the wind and also watching everything pass by.
8. Pencil drawing. It's super relaxing to me.
9. Saving the best food for last and then eating it. Also, having midnight snacks.
10. Spending the day by myself. I love my family and friends but I like doing things by myself. It's also an excellent way to recharge.
