Writing tells people more about us, than we may realize. Readers make decisions about our intelligence, level of education, breeding and morality. They decide whether we are someone who has something worthwhile to say or not.
Initially, we need to differentiate between writing and content. When we write, we do so at two levels. How we say it and what we say, both make a first impression. The best content in the world will be worthless, if the writing is careless. No one will ever hear our message.
Every time we meet a new reader, we are meeting someone for the first time. Likewise, we must always be careful which impression we make.
We need to realize the levels at which our readers perceive our writing. After this examination, we may need to tighten up in these areas, so we can make a good presentation. If we work hard to present the best stories and arguments of which we are capable, it would be tragic if we shooed our readers out the door before they could appreciate them.
