I generally have a lot of anxiety about "big" purchases (anything over 100 dollars TBH) so I end up deliberating whether it's worth it for literal months if not years before doing the purchase.
I think part of it too is that I have an aversion to having any unnecessary "stuff" in my life. Especially since my lack of object permanence means that once I put something away I'll literally forget it exists unless I have an explicit need for it.
