In the business world, no leader or manager is successful without a high level of listening skills. Psychologists say that the more talkative a salesperson is, the less successful he or she is and the fewer profits he or she makes. While communication and negotiation skills are definitely crucial, active listening remains the go-to element that provides all the tips and hints on what, how and when to say something. In fact, active listening even compels a speaker to not say anything at all if it is deemed necessary.
