My greatest fear in life is that when I die, my wife will sell all of my guitars for what I told her I paid for them.
^^ I saw that comment in some guitar forum once and it stuck with me.
I've always waffled between the idea of widdling it all down to 2 or 3 guitars and just keeping my current inventory of around 10 ish. Most people ask if they all get played and I say no. But yet I couldn't part with some of them either. Some have been with me so long they're like family members or long-time friends.
Getting a signature of a player you really like is one thing (then realizing wow, that person sure likes different things out of a guitar than I do haha) but I can admire pure motivations from someone who loves X and wants to surround themselves with every facet of that. As well as the man possessed who seems to crank out a bajillion different tones from their one dearly loved guitar.
