If you skip the pre-writing state when writing a message, its like going on a vacation without a destination. Writing experts have asserted that in order to successfully write a business message, one must use about 25% of time for this purpose, another 25% of the time for writing, 45% for revising, and the final 5% of the time for proofreading.
