Vim motions broke my brain - in the best way. I now think in verbs and nouns. Change word. Delete line. Jump to the next bracket. Everything else in life feels unkeybound.
The turning point
It was the day I typed cw in my head before editing a sentence in a text message. That's when I knew the brain damage was permanent. I've never been more productive, or more annoying to sit next to.

Yes. The first week is pain, the second week is doubt, and by the end of the month you'll be editing docs like it's a tactical sport. And yes, you'll press ESC to get out of your chat box and be very sad about it.
