I think many of us need therapists...myself included.
This dilemma is common for many collectors. Two of my buddies who live by, who have much smaller collections than I, stop by my house at different times. One is the "good conscience" and the other is the "bad conscience". I've leveraged their ideas and can now collect with clarity. I sold many items I swore I'd never sell, re-focused, but still collect most different things: autographs, artwork, 1/6 scale, and some Hasblow Marvel and Star Wars. Felt so good to "purge" many pieces I've accumulated since the collector bug hit big time in the 90's.
Manage what you can, store what you must, appreciate all you can.
