I was self-taught, mostly, on the computer I had in high school and colllege -- a TRS-80 Model 4. Also, I'm old, although the TRS-80 was already obsolete by the time I graduated high school. Of course, I also blame the TRS-80 for making me like good keyboards; it turns out they used Alps keyswitches (probably "integrated dome" switches, although they sure didn't feel like later rubber dome switches). I can still get 100+ words a minute most of the time, depending on the keyboard...
