Open an Emacs buffer, switch to Org mode, and start typing an outline. The benefit is immediate, provided those paradigms (plain text, outline hierarchy) appeal to you.
There are many features of Org mode that complement each other powerfully but that are district enough that you can climb one learning curve at a time.
I vividly remember the manual, years ago, overwhelming me! But today there are so many good tutorials the barrier to entry is quite low. Best of luck!
Highly recommend: David Wilson's System Crafters channel, Mike Zamansky's channel, Protesilaos Stavrou's channel. There's an amazing community on Mastodon.
