If you haven’t already, check out https://choosealicense.com/licenses/ . This gives a broad overview of the common open source licenses. And if you’re just starting out, one of the first things you’ll want to learn is that the licenses fall into either a permissive or copyleft category. You’ll want to make sure you understand the difference between those broad categories.
Shortly, permissive have less to no strings attached to use their code, and copyleft requires you to retain the same licensing terms meaning if you publish under GPLv3 then someone using/ modifying your code needs to also publish under GPLv3. Copyleft licenses ensure that open source code stays open source.
Id set up a static website with Hugo. You can preview and build locally. Or put it on your home network and vpn in if you need remote access to make an entry.
In your content folder you could do content/[year]/[month]/[day]/index.md, and have a _index.md in the year and in month folders so there would be pages with automatic collection of articles under that year/ month. You could also subdivide the content folder into health/ general/ shower thoughts and other “types” of journals
They have support for tags, categories, and custom taxonomies. So if you wanted to have “people” category you could, and then a “thing” category or any other sort of way to tag the content.
