At first, it is also a good practice not to install any package, and use the built-in capabilities (`magit` and `org-mode` are now part of the default installation) for a while, the time to discover what comes with the "factory defaults".
Also, for some inspirations, watching videos from `System Crafters, Howard Abrams, Emacs Rocks` to see how some people use it.
It can take a while to get used to everything, or to install packages and customize it to what other editors comes with by default, but the reward is worth.

Org is, but magit is not.
It took me about 2 weeks to get productive at first (this was in 2018), and now I use Emacs every day for a wide variety of tasks (programming and notes, mostly).
Personally, I am using Emacs for everything related to plain text files. I have benefited at previous jobs massively from already having solved some issues on my own time.
