I had never really thought about it until I was reading about how to improve my writing. If you don't read, why would you write?

As I read, I find myself studying how various authors wrote certain scenes. I need improvement in describing dialogue. So, I pay special attention to that when reading. I've read how descriptive authors are and found such a wide range that I don't know if there really a best way to do that.

The more I read, the more I learn. I'm also reading books where I can notice much easier if a scene or a character is just not explored enough. I can now see where other books lack from a reader's standpoint. What purpose does that serve me? I can write with that in mind since my reader has to understand my work and connect to the characters. If I find something dissatisfying, I'm learning what not to do.

How do you learn to write better? Read better writers to learn what to do. Read worse writers to learn what not to do. It's all about learning.
