Confident people display excellent listening skills that are beneficial to their overall success. They can offer insight and engage in meaningful conversations without overshadowing the conversation with their own opinions.
They are generous listeners who are mindful when it comes time to talk, knowing when it is best to take a backseat and let others share their stories and experiences.
Furthermore, confident people take advantage of each conversation presented to them, listening attentively with an open mind, increasing their knowledge of different cultures and beliefs.
This behavior ultimately leads them down a path through which people will no longer value or enjoy conversations with them since nothing is being learned or gained through the exchange of information.
