You are going to be ineffective in work and business situations. It's going to be troublesome managing employees or getting what you want from your boss or your clients on a daily basis. Overall, effective communication is like an engine oil which makes your life run smoothly, getting you wherever you want to be. There are very few areas in life in which you can succeed in the long run without this crucial skill."--Amazon.com.
