"Give me a man or woman who has read a thousand books and you give me an excellent companion. Give me a man or woman who has read only three and you give me a dangerous enemy indeed." This is a quote by Anne Rice. You have plagiarized. Credit must be given to whom one is citing. Why are you adding plagiarized quotes?

When my fingers hurt after too much time on the keyboard, I usually just take a 1-2 minute break and shake my hands around. :)

My tip is to practice hard every day and only concentrate in what you are typing, not anything else around you. Also, the ability to type without looking can double, triple, or even quadruple your typing speed, especially if you're reading the words that you're typing (there's nothing worse than having to read a few words off the source that you're copying and then have to look down at the keyboard to type them). Of course, the only way to be able to type without looking is to train your brain. Memorization of key position alone isn't enough. I'll have more tips coming soon! :)
