I think he meant Rookie in the kit accumulator sense. I join in with jokes about "you don't have a problem" when someone talks about a stash of 50 (or less).
But, there is a warning hidden in there.
All of the stashes you have read about with 2, 3, 5 hundred kits, or 1 or 2 thousand kits in them, started life as a smaller stash.
Somewhere before you get to 100 kits or so, we need to figure out if we are buying "everything we see that is cheap", just to have a bunch of models,,,,,or if we are buying for a specific purpose.
I have had two different stashes so far in life, three if you count the stash of "anything I can get" from before I ran off to Boot Camp. I cut the last large stash down to concentrate in my current USN and USMC theme, and this stash I have today is now larger than the big stash that made me cut down my inventory.
The one difference is that almost everything in this stash contributes to my building goal.
This post is just a long winded way of saying "make choices today in what size stash you will be comfortable with" and then do what it takes to have your stash stay that size. Trade some kits off, sell them off, or buy less often, whatever works so that your own model stash makes you happy to look at,,,,,,,,,,if your stash causes any reaction other than being glad you have all those models,,,,,,then it isn't what you want it to be. If you are happy with it at 25 or 200, then it is just the right size for you.
