Communication is key to success in relationships, work, and life. There are three main types of communication: verbal (speaking and listening), written, and non-verbal communication (body language, gestures, etc.). Verbal communication is important for discussions while written communication allows information to be recorded and referred to later. Non-verbal communication sets the tone and can undermine words if not controlled properly. Effective communication across all three areas is important for maintaining successful business relations and becoming more successful in business.
