I use Emacs with evil-mode (vim bindings) and Programmer Dvorak for my keyboard layout.

It's like anything in life, you just have to make yourself do it. There's no substitute for putting in the work and time. Sure, it's painful for the first few months, but I believe it pays off in the end.

I think the biggest thing is this: you say you try every few years to learn these editors. Don't quit next time.
