I disagree. I tried to learn Vim a few times during university. It was fun, I was able to use it productively, but it didn't stick. Neither did Emacs. I only got invested in Vim at work, where I actually had to use a text editor for a significant portion of my day (actually, ViEmu, at the time). For university work, I never used Vim for quite long enough for it to really sink in. Sure, you lose most of your productivity for a few days when switching text editors. So, I guess you should not switch editors when time is at a premium and deadlines are piling up. But you certainly need to have a good amount of time where you use the software full time, if only to build those all-important habits. By the way, this is how I learned Vim, Emacs, and (shockingly) touch typing. It worked well for me.
