Keep it simple stupid. Simple code is better than hard to understand code.

It's okay to just write code for the sake of writing, but keep in mind the idea that what if new requests comes thru; given the current state, can the code be changed easily?

Code organization is a work in progress. Can your code be easily/separately testable?

Being good at coding is subjective.

Sometimes, it may just be the tool (programming language) you are using. Try Ruby. Try Vue.js.
