The challenge with the advice is that is I want ok experiences, it works. But if I’m looking for amazing experiences it cuts them off. Lots of art is difficult until the switch that makes it worthwhile. If I followed the advice to only meet my immediate, hedonistic needs to be happy then I wouldn’t have as much overall happiness.
Especially since one great book may be as enjoyable as 100 marginal books.
Of course, it’s also important to try to figure out how to avoid all the other terrible books that just never get better.
