The best way to learn to write is to read the works of good writers
One of the best ways to learn to write well is to read the works of good writers. To begin with, just read through these works without worrying too much about the writing technique. Good argument structure and good prose can both be "absorbed" subconsciously to some extent, without explicit instruction. If you regularly read good writing (and avoid reading bad writing that crowds it out) you will find that you start to enunciate your thoughts more clearly and and eloquently without having to think about it. Don't start by reading books on writing technique; these are likely to be boring to you if you read them too early. Instead you should read novels and articles on topics that are of interest to you, written by good writers who have a clear and powerful writing style. Don't confine yourself to academic writing; read widely and include interesting fiction and non-fiction works. Most importantly, if you want to expose yourself to good writing avoid excessive time on social media and read books instead. This is likely to raise the average quality of the prose you are reading, expand your vocabulary, and train you to lengthen your attention span, all of which will benefit your reading and writing.
Once you have become "well read" by reading some good books, you should then take the next step of consciously examining some of the techniques that your favourite writers use that make a powerful impression on you. See if you can decipher and explain their technique, and explain how it differs from other writers. See if you can articulate why you find the style or technique to be powerful and persuasive. As you learn the different styles and techniques of different writers, you will expand your own writing "toolkit" and learn to find your own preferred style. In some cases you may be lucky enough to find a favourite writer who has also written explicitly about writing technique. (One of my favourite writers, George Orwell, wrote some useful articles on his writing where he sets out some writing techniques to make your writing more powerful.) When you are at a point where you are ready to practice writing yourself, you will be ready to read books on writing technique without them boring you.
For example, one of my favourite writers is the economist and social theorist Thomas Sowell. One particular technique that Sowell uses ---which makes his writing powerful--- is to gradually build up the case for a particular conclusion in an anti-polemical style, using a steady drum-beat of empirical evidence and historical examples capped off with a significantly understated conclusion. Sowell begins by setting out a hypothesis or question in a neutral manner and then bombards the reader with a mass of empirical evidence pointing to an answer, almost to the point of exhaustion. As he delivers this evidence he maintains a dispassionate and clinical tone and avoids suggesting any inference or conclusion, relying entirely on the reader to draw their own inference from the evidence presented. Once the proper inference is inescapable, he then finishes with an understated statement of this conclusion, which tends to leave the reader ahead of him in their normative conclusion. This kind of anti-polemical style is one that is contrary to what you see from many polemicists, who tend to put forward strong normative conclusions before they have convinced their reader, leaving the reader behind the writer. It is an interesting and powerful technique.
I could point to other good writers who each have particular techniques that I've found to be useful in writing. Some strong writers that I've found to have helpful writing styles and techniques are George Orwell, Thomas Sowell, Jean-Françios Revel, Ayn Rand, Michel Houellebecq, Noam Chomsky, H.L. Mencken, T.S. Eliot, and Mark Twain. (There are probably plenty of others that I'm forgetting now.) In any case, the above example is just one writing technique that I have observed amongst the best writers I've read. By reading good writers, absorbing their works, and then learning the techniques they use expliclity, you can expand your "toolkit" for writing and learn to write
