Pick up a book/movie. But here are the terms and conditions. Don’t pick it up if it was suggested to you by someone else, don’t see reviews, IMDB rating or anything related to the movie. After finishing the movie/book put down all your thoughts on a piece of paper. How you felt, why the movie was a masterpiece or a piece of garbage, etc.
Most of the times what happens is we watch any movie because it was suggested by some art connoisseur suggested it, the reviews were mind-boggling or it had high IMDB rating.
The views which you hold after watching the movie aren’t really your own. (Joaquin phoenix nailed it, Tyler Durden is literally me, Masaan is underrated). But still you feel part of an “intellectual minority with a different great taste in art.
So, try seeing whether the thing really piqued you or not. Generally too avoid confirmation bias, subjective validation and preconceived notions.
