First: writing has other tangible benefits! Journaling can get difficult thoughts / stressors out of your head and on paper, helping you process and move past them. Taking notes improves comprehension, and is also (often) of higher value in a professional context than most people realise.

Things I've heard writers / bloggers / etc. in my life say about writing:

- There is no magic bullet; you just have to practice, practice, practice and be willing to throw away large sections or even entire drafts. Most people, including famous authors, write large volumes of crap. - If you're explicitly looking for an audience, you have to test with that audience! Get feedback early and often, and use that feedback to improve what (and how) you write. (If you have any product / design / UX training, you'll notice how similar this advice is to best practices in those fields!)

(On the second point: using Notion, Google Docs, or any other tool that gives you an easily shared link and allows inline commenting is a great way to get useful feedback!)
