The part that was best for me was someone taking so much time to document, screenshot, and close the loop on most parts of managing information with org-mode.
I hope it treats you well!
Something I would also recommend: try to setting things as file-local variables or org comments at the top of an org file instead of dumping in init.el. Setting the configuration globally can make things confusing when you're just learning things.
I use org-mode for my entire GTD workflow (calendar Agenda, next-actions, tickler, maybe, and projects), I use it for capturing quotes or blocks of text that I really want to save for later (my spark notes file), I use it for capturing my "recipes" of anything (software, realizations, food, etc...) in my grimoire file, I use it for capturing notes or thoughts while I'm reading books (with nice capture templates for guiding me through setting the page # and paragraph # in the property drawer), I use it for all of my web bookmarks (I have a bookmarklet integrated in Chrome that auto-fills fields in the capture template for the website), I use it for articles in my To Read list with a Chrome bookmarklet for auto-filling the capture template, AND I use it for my spaced repetition routine with org-drill.
I also use it extensively for work on-top of all the above. I have a capture template for my team's weekly standup meetings, I use it for taking notes during meetings and structuring action plans, etc...
The capture templates, org-protocol for external programs to activate a capture template and pre-fill with data, customized Agenda views (so I get a nice "HUD" for long-running tasks + my 4 day agenda), and refiling (this is one of my favorite parts of org-mode!!!) are absolutely invaluable and an incredible tool for my productivity.
Nothing matches it in breadth and depth, nothing. And as is the case w/ Emacs, you can customize everything to suit your workflow or make tweaks - maybe you have a great idea for improving something! For me I was able to create a highly customized Agenda view specific to my personal deficiencies (I forget about long-running important tasks that aren't a "SOLVE IT TODAY" task).

Meanwhile, FWIW, I'm happy to report (the age-old boring truth) that consistently using it in my daily workflow for the last one year -- didn't even break for a week, except when on holidays -- resulted in making the habit stick.

Seeing how someone else who lives on the platform does their configuration helped put it in perspective, then I just cherry-picked the ideas I liked from there in building my own.
Give it a try the next time you need a README.md. Make that a README.org instead.
