Good writers are storytellers who organize information in order to communicate a message. A big part of “good writing” is editing, distilling the message and clearing away the extraneous clutter. The “good communicator” also has the ability to experience the work through the target audiences’ point-of-view.

Some people seem susceptible to a sort of “stage fright” when it comes to putting words on paper. Clear writing is a good indication of clear thinking, but clear thinkers are not always clear writers.
