I've been using Emacs for everything since highschool and through University and my career. The best way to get used to it is to bootstrap with tutorials and then just keep using it.
I learned a lot about it from doing basic projects and then homework assignments, and then at work.
I started out by following basic tutorials, like this one [0], and working my way up. You may want to find a guide to get themes setup, and some rough edges ironed out.
Alternatively, you could dive into distributions. I highly recommend Spacemacs, and have written an article about it [1]. It is a lot of learning especially if you're familiar with vim. The github page is also a great introduction [2]. I would recommend using the develop branch over master, as master tends to be very stale.
I have also heard good things about Doom emacs, another vim style distro.
