I used to type while looking at the keyboard. I would tell people that I used all ten fingers. But when I started to think about it, I noticed that I used all the fingers on my left hand--almost in the way you're supposed to--while my right forefinger would hop around the right side of the keyboard like a woodpecker, and the rest of my right-hand fingers stood idly by.
Then one fine day I told myself, "If you (I?) are (am?) going to spend so much time in front of a computer, might as well learn how to type." So I did. I used goodtyping.com. And when I finished their lessons, I practiced at keybr.com And the rest is history.
I consider the decision to learn how to type properly one of the few wise things I have done in my life. It made life so much easier. Among other things, it transformed my online chatting experience. In the pre-touch-typing days, I was always rushing to get my thought across before my chatting partner said something which would render my thought irrelevant. And as I typed, there was always this pressing question: what if he already wrote something? What if I'm too late?
Now I can read and write at the same time. Chatting is purely pleasurable.
Now, whenever I see people pecking at their keyboards one letter at a time, instead letting their fingers flow to the sound of graceful tapping, I feel like shouting at them, "Go to goodtyping.com! Release yourselves from the bondage of staring at your keyboard, when the real action is on the screen!"
