Research has shown that only 7 percent of our communication consists of words--55 percent is attributed to body language and 38 percent to tone of voice. This is what's called the 55/38/7 formula. Knowing how communication works is tremendously useful to anyone, in business and in life.

To communicate effectively--personally and professionally--it's extremely important to choose your words wisely. Words have a way of building people up or tearing them down.
