Thesis

Here are two possible thesis statements:

• When composing a writing artifact it is curtail to proofread, be concise, and most importantly know your audience, 

• To be a credible writer it is important to maintain clarity, create the preferred tone for the document, and to have the perfect writing style for the set audience. 

I also have a small list of the main key words that I picked up on while interviewing:
know your audience
proofread
writing style (always changes)
concise
clarity
tone
credibility
