I think Ben's a lost cause....he was warned 
The trick is.....Don't fight it! But it IS helpful if you can have fun with engines in the low $ category,(D5) class or similar.. also helpful if your handy at building new shelves for storage. I am 6 foot 6 inches tall so I can even construct shelves on the ceiling Without a step ladder.
AND...I am not currently keeping a wife.....SO.....I got NO adult supervision....some might Even label me "The Perfect Storm" 
All joking aside, a big part of my addiction is: I have Always been drawn to miniature mechanical things that really work, Also I have ALWAYS liked to take things that are shiny but perhaps not always super well executed(think Wilesco-ish) and purchase used at low cost and see if I can make it just a little bit better. Modifications are they Real fun for me as well as converting things to power with my modified engines....yup, that's me.
Ben I could have written every word (above) and it would have been true for me as well , although I'm only 6'1" I have have a 2 step stool to get to the top shelf in the shop. 😊
Ps , I didnt let my wife see the "I am currently not keeping a wife" line...she would have taken a dim view of that one 😎👍
