go on an aimless bike/ride/walk - move your body, do it for as long as you feel like it, discover new places near you weather that is a frog or a cafe

watch a new movie/read a new book/listen to a new album - get inspired, excercise having opinions and longer attention span, break out of consuming content and make a choice about what you want to expirience

create something in a medium i haven't used in a while - get out of a habit, rekindle a flame you haven't been upkeeping, making a friendship bracelet counts

go have a fun new drink/snack - arguably most important, have a little treat without rush, slow down and focus on physical sensations, treat yourself in a way that isn't landfillcore

meet with friends and/or go to a place where you meet strangers - human connection is good for you, (maybe some casual sex if you like that/try something new with your partner)

make some bad art - create for the sake of creating without any expectations

play an instrument - this can be anything that makes you reach a kind of flow state

go see something you haven't yet - get to know the cultural/geographical map of your area, this includes events, places, or just anything that makes you go out of your way to expirience something new, can be like a viewpoint or it can be a museum exhibit, anything you find cool
