This mirrors my experience. When I was a teenager I could type rather quickly using only two fingers on each hand. I figured I'd be typing a lot my whole life and it'd be easier to re-train proper typing habits on a whole new layout rather than trying to adapt my QWERTY habits I picked up while playing Runescape in elementary school.

It took about a month to learn, but on the side it largely fixed my QWERTY habits too, and I can freely switch between them pretty easily.
