Detailed Answer
Writers often type at the speed of thought (60-80 WPM is ideal). To improve: 1) Separate drafting from editing – don't backspace; just type. 2) Use distraction-free editors (FocusWriter, OmmWriter) that hide spell-check. 3) Practice with transcription (type audio) to train rapid output. 4) Learn to type punctuation without thinking – commas, periods, quotes should be automatic. 5) Use text expanders (PhraseExpress, TextExpander) for common phrases ('btw' becomes 'by the way'). 6) Do daily 5-minute 'free writing' sprints where you type non-stop. Many writers plateau at 40-50 WPM; breaking to 70 WPM can double daily word count.
