I upvoted the parent and want to emphasize vim key bindings. This is not necessarily vim the editor, it's your editor of choice in vim mode. Learning to use vim is like learning to touch type: it's initially a pain, but it's hard to ever go back once you've mastered the basics.

If you haven't learned to touch type (it happens, I didn't learn until I was 22), then first learn that, then learn vim.

FYI: Remap your capslock key to escape to use Vim more effectively.
