TIPS TO REMEMBER: 

• Use few words as possible for maximum efficiency. Less is more. 
• Ex: In that moment, he expressed feelings of angst and stress is better off written: He was feeling anxious and stressed.
• 10 words brought down to 6.
• A great writer knows how to use the right words, not the most words! 

"Good writing starts with a profound respect for words-- their denotations, their connotations, their force, their rhythm. Once you learnto respect them, you'll develop a passion for using them thriftly," -John R. Trimble, Writing With Style
