How to handle the urge to build a MISB LEGO set for LEGO "INVESTORS"

For my fellow LEGO enthusiasts who have children (biological or otherwise) who may be reluctant to open a MISB LEGO set when considering long term investment.

I frequently buy random piles of bricks and blocks
& have a room dedicated to sets & MOCS.

I spend hours each week sorting these lots
& am delighted to find CMF robots.

I tenaciously sort, research and build
so I can get my eBay “Active Selling” list filled.

While frequently stalking every toy clearance isle I find
enjoying the adrenaline rush when I see a 50% off sign

I load my shopping cart with boxes of this building kit
imagining great profit if I can take the time to sit on it.

Wondering if these LEGO sets will do well,
as we all know, only time will tell.

Finding space in my house to store all of this
is frequently hindering my home owner bliss.
I’m wondering how long I can keep doing this!

But the moment a child enters this magical place
and they have a huge smile upon their face,

I'm reminded of infinite imagination, pure joy & possibilities.
How does one place a $ value on these???

LEGO literally translates to “play well”
& the value of play trumps the value of sell.
