How do YOU know it's a Keeper?

I've slowly learned to never make proclamations that I'll never get rid of a particular guitar or never stumble over an instrument I like better than the ones I already have. If you'd asked me a couple years back I'd've said that I'd never get rid of my Seagull Artist Studio -- in fact, I'm certain I could quote myself saying that if I went back and searched old posts here.

But then I took a chance on an Eastman E10D, and it sang to me so immediately and strongly that it caused me to shed my Seagull Performer to help buy that. The E10D became my main guitar to play out, essentially replacing the Artist Studio in that role. I went looking for a spruce/rosewood Eastman to see if it might similarly impress me. The E8D I purchased more than did so, and I sold the Artist Studio to finance that. For solo gigs, I now use the E10D (tuned in DADGAD) and the E8D (tuned standard) along with my Guild 12-string (tuned in D standard).

I still have a 2018 Guild OM-140ce (spuce/mahogany) that's my office/couch guitar -- but I'd willingly sell it if I found something that spoke to me more. To me, it's mostly about tone: I want to feel the bass through the back of the guitar as I play (which is why I prefer dreads and also why I love the Guild 12-string, which has a jumbo "F" body); I want the highs to be clear and sparkling; I want the guitar to project. I also want the plugged-in sound to be natural and non-quacky (which is why I put the K&K Pure Mini pickup in both Eastmans, and am tempted to rip out the undersaddle piezo that's in the Guild OM-140 and put a K&K in there, even though I rarely-to-never play that guitar plugged-in.) 

Sometime this week, assuming that the guitar's still there when get the chance, I'm going to go to the local Guitar Center, which has a used Eastman AJ617 (Jumbo body, solid Engelmann spruce top, and solid mahogany body) and play it. If the guitar's in decent shape and I find myself bonding, the Guild OM may well go so I can buy that. But we'll see.

All of which is a long-winded way of saying that I'm leery of stating that any of my guitars are 'keepers' except in a potentially temporary sense, even though I'm certain some of them will outlive me at this point.
Not to be morbid (just realistic), but none of us are 'keepers' either. 


EDITED TO ADD: If I had unlimited funds for guitars, I would have held onto the two Seagulls I've already sold. But: a) I don't have unlimited funds for guitars; b) I can only play one guitar at a time, which means some of the guitars would just sit in their cases neglected and I'd rather they were in the hands of someone who wanted them; and c) Denise is willing to go with one-in, one-out for new guitars, so four acoustics are currently my limit...
