So, there you have it. You don't need to learn Emacs at all if don't want to, just learn Emacs Lisp first! Although Org mode specifically has a rather unpleasant API.

a bunch of them work in bash too, ctrl-r for reverse i-search of your history.
You probably already know more than you think, and learning 10-15 basic commands will get you a whole bunch of utility all over the place.
Evil mode is still not set up enough like vim for me to use in my every day work, though. There are a few gotchas that are different. So I use vim as well as emacs. I just change windows in tmux when I want to use org mode. The only real downside is memory usage and it is inconvenient if you want to us capture in org mode (because you have to change windows).
I'm slowly setting up Evil to support my workflow. I don't think there is anything I can't do, it's just a matter of implementing it. Rather ironically, I used emacs for 20 years before I switched to vim. I have discovered that I prefer modal editing and having a grammar to describe my edits rather than directly editing things. You would think that I could switch back and forth, but it completely blows me up. I seem to have learned emacs keystrokes and vim keystrokes in different parts of my brain...
I actually don't use org mode much though. It's one of the nicer tools I've tried, but I'm just not an organized person.
Pretty much every organizational tool I've ever tried is really good at helping organized individuals become more organized, but do little to help those who are disorganized.
I am extremely disorganized too, and I have seen org mode helps me in the getting back business - though you do have to invest seriously in org mode first to be comfortable enough in it. But org has the answer to this too : org-drill.
