When you type at the keyboard, looking at the screen, you are actually double-tasking. Your eyes will continually watch the words, looking for errors, consciously editing. When you should be focused on simply capturing your genius. You can overcome that tendency by using a wireless keyboard and getting away from the screen, closing your eyes as you think, or merely staring off into the stratosphere out the window. Get away from the computer screen altogether until it is time to revise and edit those things you captured. Then focus on that single task.

Which is why I use a digital voice recorder as my notebook and speech-to-text software that converts the audio files to text files on the computer. I'm off getting a 2nd cup of coffee and relieving myself of the first while the computer is converting my creative thoughts to text on screen.
