Yeah while I'm not totally on board with some of the descriptions I think this
list of things you should read to say you did
plus
Wow. A grab-bag of "Forced on you in middle school or high school" books, a few "classics", some crap that trendy managers read to make up for a lack of actual business skills, a handful of readable work, and a smattering of pieces of "literary" tripe.
Pretty much covers the nature of the list quite well.
Most of the books on the list are pretty easy to read but really few of them are all that spectacular in the greater scheme of things.
However some books it might be worth reading divided by the three decades leading up to 30
