When I learned to type back in the 1990s, I used Tipp-Ex (a correction fluid, an opaque fast-drying white liquid) to cover up the keycap letters on my keyboard, to force myself to move away from four-fingered typing with occasional keyboard glances.

It wasn't enough though. What pushed me over the edge though was switching to Dvorak. That forced me to learn. I can type Qwerty, just extremely slowly, but the only place I ever need to use a Qwerty keyboard these days is the touch keyboard on my phone.
