I couldn't get into the whole zettelkasten or second-brain trend. I didn't like using Logseq. Obsidian is proprietary.
What's working for me is writing a daily journal/diary in a TiddlyWiki file. I seldom read what I've written in it. It's just that writing brings more clarity and allows time for some quiet reflection.
There are other kinds of journals too - engineering daybook, gratitude journal etc.
