I've got mixed thoughts/feelings (theelings? foughts??) about stoicism but my brother gave me a pretty damn cool coin that he got from the creator of a stoicism podcast or something like that. The heads side (there's a profile of a guy with the classic bearded ancient guy look) says Carpe Diem and the tails side says "Some things are in our power / other are not" along the rim with "Persist and Resist" in the center between two columns. It's a bit bigger than a US half dollar and I always keep it in my wallet.
