I tend to focus only on the bad things, so it is really helpful for me to intentionally notice the way things are good alongside the bad

This reminds me that one Christmas (probably 25 years ago now, lol) I gave my family and some of my friends letters of appreciation, and it was really good and happy-making to focus on all the things about people that I liked and valued, instead of getting stuck on the petty annoyances. :-)
