I learned to type correctly at the age of 33. I purchased a Das Keyboard with blank keys and did not allow myself to work with another keyboard. I used this site as often as I could remember to track my progress and I went from typing about 35-40 WPM looking back and forth at the screen with 4 fingers total to typing the correct way at 40-50 WPMs over time. At least now, I feel more and more comfortable every day.
