> There would have to be a tectonic shift in understanding to get me interested in reading another book.
Maybe I misunderstood this. I thought you meant that you would need a mindset change before you would be willing to consider reading another book. In that case, suggesting that you may never get that shift without reading is a bit of irony (a Catch-22 if you will).
However, if you meant that you wouldn't read a book unless you knew there were some kind of major insight on it for you, then:
1) my statement probably did come off as trite to the point of deserving sarcasm, and
2) I feel bad that your mind is so closed to considering new opportunities.
You're still being condescending. Re-read your last line.
My point is that opportunities are everywhere and never stop coming, and so one must invariably pick and choose where they'll look. It generally makes for a calmer life to not get too worked up over FOMO, because it's incredibly rare to miss out on anything really important in the grand scheme of one's life.
