under studies, broader interests like I love learning!, big 4x4s for liberal arts and STEM, and 1x2s for social sciences, natural sciences, and medical & health. Some other fun little quips: stay curious!, question everything - learn anything!, ask silly questions get silly answers, and raah! I will never catch up on my homework!
also a plug for the trades! tradesman, craftsman, electrical, plumbing, HVAC, build something new!, see a problem? get up and fix it! (maybe with a pet in a hardhat wearing a hammer?), build the world you want to live in!, I made that!
a big 4x4 "creative" to go with the artist and writer stamps! a musician stamp, maybe content creator and video editing too? "I love arts and crafts", and a funny one -- in big letters " brilliant ideas!" and in small letters "with zero follow-through"
personality traits like "stubborn as a mule!" with an actual mule

and "creative problem solver" or "crazy problems need creative solutions!" and for its positive twin, "together we can save the world!"
I know some generic disability rep/awareness has been brought up, I would LOVE little stamps for general stuff like "neurodivergent -- please be patient!", "I get confused", "I get distracted", "words are hard!", "memory like swiss cheese!" etc. because that fosters better interactions and understanding! I would LOVE LOVE LOVE! one that says "I have no idea what's happening right now

"
On that note I second a plural stamp because I see the plural community has a presence here -- if you want to stay neutral on discourse use phrases up to interpretation like "it's crowded in here!" (similar to the "two heads are better than one!")
I think small symbols for all of the major religions would be tasteful so long as you include a variety (just like we have Christmas AND Hanukkah). On that note "I practice magic" and "I believe in magic" just like we have I believe in fairies would be nice!
dog/cat/pet mom/dad/parent would be cute
