One of the great small book I read about writing is: Style: Lessons in Clarity and Grace (https://www.amazon.com/Style-Lessons-Clarity-Grace-12th/dp/0...) It is very different from Strunk&White book in that it does not address things like whether you should place a comma or not, it teaches you about how to present you idea clear and easy to understand. In short write less like Friedrich Hayek and more like Ray Dailo. The former uses much more beautiful long sentences, but the latter's essays are more easy to read, and clearer in delivering the author's ideas.

I've learned quite a lot about editing from "Style: Lessons in Clarity and Grace." It presents some tricks to restructure and improve the flow of sentences, and through that process, to generate the momentum to really think about what you want to say.

I am reading "Style: Lessons in Clarity and Grace", have you read this?

EDIT: link to the book: https://www.amazon.com/Style-Lessons-Clarity-Grace-12th/dp/0...

I've learned a lot from:

* Reading lots of books on writing. Probably this (https://www.amazon.com/Writing-Web-Creating-Compelling-Pictu...), definitely this (https://www.amazon.com/Style-Lessons-Clarity-Grace-12th/dp/0...). Got both from local library.

* Reading lots of other books I got from library (on writing and marketing).

* Practice, coupled with observing results on google analytics.

* https://practicaltypography.com/typography-in-ten-minutes.ht... for basic design.

* Free content on https://stackingthebricks.com/ (there's a lot, although it's mostly lead-in to paid content).

The last one in particular motivated me to write based on research, which resulted in massively improved results.

"Style: Lessons in Clarity and Grace" is better than "The Elements of Style".
