I do think sometimes reading books about coding might actually make you worse since you might misunderstand the rules gained from there and try to use them everywhere even if they don't make sense.

So you need some sort of built experience that will allow you to consider those rules critically, and only add them to your toolset if it does seem to make sense for you and you understand why, you have past experience where you think "oh - that would have helped me a lot".
