Recommended books on writing?

I love following this for everything I write (sales letters, blog posts, video scripts, etc): https://expensiveproblem.com/building-the-perfect-sales-page

Also The Brain Audit is a great read and will teach you how to write to sell: https://www.amazon.com/Brain-Audit-Customers-They-Dont/dp/0473175045

Hey man,

Like your enthusiasm. Here are some resources I've used to take my writing to the next level.
On Writing by Stephen King.
Elements of Style by Strunk
Everybody Writes by Anne Handley
The Gary Halbert Letters by Gary Halbert. (No longer publicly available as a single PDF. I've got it in my drive. Hit me up and I'll share the link)

If I may critic your post, here are 2 things I would pay attention to:

• Avoid repetitions: "Most of my writing skills come from writing dozens of essays" doesn't read well. You could simply remove the second 'writing' and have "Most of my writing skills come from dozens of essays". It might be a similar problem in your first paragraph.

• Avoid starting a paragraphs with 'I'. Especially in emails, it's not about you, it's about the person you are talking to. Although in that case you are asking for advice, so it doesn't sound as bad, but worth building the habit.

In my opinion, writing is 20% writing, 80% re-reading and re-writing. Just like code would be. So you spend most of your time re-factoring. (if only there was unit test tools for prose!)

So to continue comparing writing prose with code, books can be a great starting point, but reading other people's work can be just as good. Just like you would learn advanced ruby from reading rails code, just be more self aware when reading the posts of an author you like. Compare those to authors you like less.

My qualifications~ my published books sell 250+ copies a month and I am frequently praised for my writing abilities.

1, Don't use profanity in your writing until you are the level where you know the rules so you know when to break them.

2, Explain jargon. IELTS? What's that? Why should I care? Your writing has to talk to exactly one person at a time.

3, Get a copy of Strunk & White. Follow all the rules.

4, Remember the principles of SUCCESs: tell a simple, unexpected, concrete, credible, emotional story.

I'm not much of a writer myself, but I've heard Tim Ferriss speak highly of:
'Bird by Bird: Some Instructions on Writing and Life'
'On Writing Well: An Informal Guide to Writing Nonfiction'

Not being a native English speaker myself, I think I know the problem ;)

My advice would be as follows:

1. Identify successful blogs in our area of interest and look at their writing style. How do they structure their posts? How do the address their audience?

2. Practice. Write a short post, review it, edit it. Try to get feedback, preferable from a native speaker.

3. regarding your original question, a book on writing that I personally found useful is "On Writing Well" by William Zinsser.

This is slightly unrelated (i.e. not books, but apps instead). I have made a small app for organising your thoughts and turn them into text. I'd be really happy if you would give it a spin and let me know what you think: https://getmindmaps.com

The idea is quite simple: You first brainstorm, then you organise and finally you write.

Several short sentences about writing by Verlyn Klinkenborg is a fun and engaging read. It really demonstrates the power of simple writing.

https://www.enchantingmarketing.com/free-writing-course/ Henneke is a terrific person and every her lesson was a revelation for me.

So as other people mentioned, "On Writing Well" by William Zinsser is a great book. It's a perfect choice for you as it covers writing nonfiction texts in general.
I also recently read "On Writing" by Stephen King. It's a great book but mostly focused on writing fiction. Read it only if you have time and interest on the subject.
By the way, Stephen King recommends "The Elements of Style" by William Strunk Jr. He describes it as a classic book of writing. I didn't have time to read but plan to do it soon.

Also, if you want to improve your writing, there are two great tools to help you. The first one is Grammarly, an app that lets you fix your grammar and spelling. The second one is Hemingway Editor, which serves to aid your writing style. This means your less complex sentences, avoid adverbs and passive voice.
I use both tools for each text I write online. They work perfectly in combination as each tool serves different goal.

His writing style is VERY casual, but smart - and it converts.

His stuff is easy to read and he breaks down everything he does.
