I used to really be into collecting certain things - but now I don't care that much if I have them anymore.

Why is that? I make more money now - could it be that I could just buy something if I needed it?

Things I collected that I've kind of lost instrest in:
Philip K. Dick books
Greg Egan books
Devo stuff
Vinyl (in general)
CDs (in general)
The Roots stuff (CDs, vinyl, etc.)

Or is it that these are all available in non-physical format?

Anyone else ever lose interest?
