When my fingers hurt after too much time on the keyboard, I work on other life skills. There is after all more to life than typing. Cooking, Physical Fitness, Spiritual Growth, Higher Education ETC.:)

My tip to improve your typing speed is to type when you feel like it. You'll do better when you enjoy it. :)

My tip to improve your typing speed is to... practice a little every day. It is easier to "sprint type" on shorter quotes. The short one's are where I get the most WPM. : )

My tip to improve your typing speed is to... focus on your accuracy and make sure you practice daily or almost everyday. Your brain will make the neuron connection's through practice over time. Also I like to open another window and put some instrumental music on, it help's me get in the groove and loosen up, which makes typing feel more like second nature. : )
