At first you were frustrated a lot, and far less productive. Your browser history was essentially a full index to the online Vim documentation; your Nano and Pico-using friends thought you were insane; your Emacs using friends begged you to change your mind; you paid actual money for a laminated copy of a Vim cheat sheet for easy reference. Even after weeks of training, you still kept reaching for your mouse out of habit, then stopped with the realization that you’ll have to hit the web yet again to learn the proper way to perform some mundane task that you never even had to think about before.
But as time went on, you struggled less and less. You aren’t sure when it happened, but Vim stopped being a hindrance. Instead, it become something greater than you had anticipated. It wasn’t a mere text editor with keyboard shortcuts anymore—it had become an extension of your body. Nay, an extension of your very essence as a programmer.
Editing source code alone now seemed an insufficient usage of Vim. You installed it on all of your machines at home and used it to write everything from emails to English papers. You installed a portable version along with a fine-tuned personalized .vimrc file onto a flash drive so that you could have Vim with you everywhere you went, keeping you company, comforting you, making you feel like you had a little piece of home in your pocket no matter where you were.
