It's really simple and not complicated unless you want it to be, but then you watch a video about one Mega User who is really into the System and get demoralised by the amount of crap and whizbangs you see.
I use a semi-bullet journal method in my Obsidian notebook for work, but it’s even more basic than what Ryder Carroll outlined and I don’t care that much. Not caring is extremely helpful.
Now my system is geared towards minimal friction from "crap, I need to remember this" to actually storing it in Obsidian.
Currently I have a Keyboard Maestro macro that activates when I double tap the key on the left side of 1 on my keyboard, which then will activate Obsidian (or start it if needed) and brings it to the front with a QuickAdd dialog where I can write down whatever I was thinking about.
QuickAdd will then append it to an Inbox file with a timestamp. I might take a look at it later or maybe not, but at least it's written down _somewhere_ =)
On the Mac I was using Hammerspoon for this. On Windows it would have been something like AutoHotKey.
Your goals are not the same as the person making a Youtube video. Nobody's going to put down "Highly Proficient with Obsidian" on their resume in hopes of it giving them an edge in the job search.
A cottage industry of people have thus sprung up around providing this content, and recommendation algorithms and search results wind up being dominated by this content.
For a new user who's just heard about something, the path is often straight to this content, which then leads some to bouncing off of it because it seems too daunting.
