The post is from 2010, today in 2019, I'd say that first step could be to install a vim extension in your already existing IDE/editor, VSCode and Idea have good enough vim plugins to start learning insert mode and moving around, and even allow you to search and replace :%s/termA/termB/g You can also play Vim Adventures[1] if you want to be even more playful.
