We are pretty similar really, think alike and all.
I came from a family who didn't have much left over after all the necessities were paid for and so I've always had a need over want purchasing ethos and have worked towards making what I have last longer, or to repair what I have so I do not have to spend needlessly. This doesn't mean I don't have good things, nice things, I do. What it means though, is that as my income increased over the years I applied that ethos and it ended up seeing me focus on quality not quantity, and I have some very good quality things.
Having said that, experiences are what's important as you point out and for me that means travel - I've been all over the world on multiple occasions and it's what I found/gained through travel that I think of when I think about what I have.
I hear what you're saying about guns, it's the same with other things (cars, trucks, watches and so on, but I have always worked to apply the need over want. Sure, I've been unsuccessful and have ended up with more than I need at times but generally it's worked out that I have had what I needed, when I needed it, and I'm ok with it.
