I'm like this too. At this point I'm a lot more excited about amps and cabs than I am about different guitars. In a way, I'd almost consider myself an amp player more than a guitar player.
I was lucky though. 26 years ago I found my #1 (PRS Custom 22 with EMGs) and I still love the thing. I've played it almost every day since, and it's still my #1. I've bought, really liked, and kept other guitars but that PRS is and has always been home base for me.
Amps and cabs though? I feel like there's always new tones to chase. That's where the excitement is for me. Who knows, maybe if I'd have found the "perfect" amp and cab setup for myself 26 years ago I might be all about chasing guitars these days. However I doubt it because while to me it feels like there is a kind of platonic ideal for a guitar, with amps it's more complicated, like there's more of a moving target there, so there's more reason to chase different tones from amps and cabs.
