> Why
this word,
this scene,
this character, and not some other one?
The "why this not that, even when it looks like that would do just fine" style of differential analysis is an exquisitely powerful analytical tool. Asking this question is probably the single most powerful method I know of to generate deep thought, in absolutely any aspect of life. If you haven't tried it... go for it!
(Sample question: why'd I choose the word "exquisitely" in the above sentence?)
> In the short term, thinness prevails. ... The real question is not “which of these things looks nicer when you look at them for two seconds?” but “which of these things will stand the test of time?”
That tracks with another thing I've noticed I approach differently. I've recently joined a book club and everyone loves to talk about how many "stars" they gave a book. I've never really been able to rank things like that. Aside from there being no such thing as a total ordering of books (or movies or ...), who's to say what five stars from you means, compared to five stars from me? Instead I've started thinking about books in terms of "book of the month", "book of the year", "book of the decade", "book of the century", et cetera. Is this going to be the best thing I read all month or all decade? Am I going to remember this for a year or forget most of it next week? Is everyone still going to be talking about this one in 80 years? I think that's a much better scale than "one to five stars (but actually three to five stars)", and much more interesting. It also bakes in both the inherent subjectivity and inherent fuzziness really well.
(Yes, some things... plenty of things... are thin enough to be candidates for "book of the day" or "book of the hour". Few things are forgettable enough to go below that, though there have been some attempts; mostly at that level things underflow and you get in to Mystery Science Theater 3000 territory, which is its own special kind of thing.)
