I raised my average wpm from 60 to 110 by:
- Memorizing the keyboard layout I type in (QWERTY)
- Typing plain text everyday
I never learned to touch type using the home row. I still don't use the home row when I type. Memorizing the layout helped me a lot with keeping my eyes off the keyboard. Once I could visualize every key in my head, it took me ~1 month to go from 60 to 90 wpm average. It took me ~2 weeks typing 15 min/day everyday on
typeracer to get the last 20 wpm.
It's worth the effort, if you work on your computer everyday.
