What small and big things did you do to improve your looks?

This year I am investing in my looks, I rate myself around a 7.8. I am starting with small things such as getting a self-care routine together (nails, eyebrow threading and pilates) , diet (work in progress) and trying to adopt a new hairstyle. But with the big things I am gonna whiten my teeth and straighten them and possibly get into fillers (I want to slim down my face). I wanted to know what things you did to improve your looks , whether they are small or big?
