A sense of which writing is better is the very thing that reading lots of books helps you discover.

And I don't think only reading "quality" literature is necessary, you just need to not mindlessly read the same thing over and over again.

I've found my enjoyment of all media improved massively when I stopped trying to find what made it bad and started to look for what made it good.

Though some techniques start to feel cheap, like how fast food makes everything palatable by being crunchy salt and sweet.
