I think every collector would go thru the "buying for the sake of buying" phase of their collecting.
that's the most exciting yet terribly draining phase of collecting as it becomes more of an addiction.
this was like what? 15 years back when i was snapping up anything TF i could lay my eyes on.
worst bit was buying multiples of the same figure (i did that the most with Beast Wars where I had every figure ever produced by Hasbro & Takara in duplicates)... 1 to open, 1 to keep MISB, 1 to trade, etc, etc.
the MISB BW lot i've still kept to this day (at me folks') to remind me of that crazy phase of my life... every MISB BW bot had a unique acquisition story
looking back now, i'm amazed at how carried away i was.
i pissed off the ex-girlfriend then as i dragged her shopping for toys whenever we had the time and my room was literally filled to the brim with toys!
I had to place my bed in the middle of the room as i'd bought shelves for all 4 walls to display and store my collection (which seriously drove the ex insane! LOL).
these days, i'm older (and hopefully a little wiser) with me own family and toys are no longer a priority.
i just buy what i like after bills (they never end) have been paid and essentials for the family have been taken care of... which means I don't get to buy much these days!
