I will say that, while I agree with this advice, my upper limits of high end, mid tier, and everyday drinker have drastically changed as I have progressed through my career. What was previously unobtainable is now a celebration wine and what was high end is now a weekday drinker.
If I was making in 2008 what I am making today my cellar would look drastically different. But this probably isn’t a unique circumstance.
same!
The good thing is that both of us are at ages (I’m including myself just to feel younger, deal with it) where people start collecting while we have this thread and plenty of drinking behind us to change courses if we need or want to 
I’m generally happy with my collection. I don’t have very many bottles that I look at and wonder what I was thinking and how will I get rid of it. Some, but at most a few percent of my holdings. I still would have been better served drinking a lot more before I started cellaring. Of course I completely ignored that solid advice many people gave to me. But luckily it’s mostly worked out ok.
Also, just a couple of years ago for us a $30 bottle was a special occasion wine. Now our usual “daily drinkers” are in or over that range. (We don’t earn too much more now than then. I guess we just had to get used to it.)
I’ve managed to keep my cellar bottle count under 250 which means I rotate through them fairly quickly so I’m not sitting on a bunch of stuff. That works well.
That does come with some downside since nothing has much age and there isn’t a case of a specific bottling to taste over time. I don’t think I have more than 2 or 3 bottles of any single wine and they are sparklers.
Great minds!
Speaking of which, I’m a bit remiss on something - IG chat coming this weekend. 
Probably for most people. But then there are those whose income is the same as 2008 but the wine they bought earlier has inflated.
