What do INFJ'S purchase?

I was thinking about this as I got older. 35m INFJ. Always thinking about survival and purchasing things that actually are useful in life or may deter life in the future.

I remember I wanted to buy a PlayStation 2 for old school gaming and nostalgia. Then I realized I probably should buy a carbon monoxide alarm first. Buy a tire inflator for my car, a jack, a jack stand, a spare tire, a first aid kit then my budget is all used up for the month. Not exactly flaunting the money with my broke ass, however I always feel like I need to be prepared for myself and others.

I was curious if others do the same or what you buy regardless.

Thank you.
