While traditional psychologists specializing in close relationships have focused on relationship dysfunction, positive psychology argues that relationship health is not merely the absence of relationship dysfunction.  Healthy relationships are built on a foundation of secure attachment and are maintained with love and purposeful positive relationship behaviors. Additionally, healthy relationships can be made to "flourish." Positive psychologists are exploring what makes existing relationships flourish and what skills can be taught to partners to enhance their existing and future personal relationships. A social skills approach posits that individuals differ in their degree of communication skill, which has implications for their relationships. Relationships in which partners possess and enact relevant communication skills are more satisfying and stable than relationships in which partners lack appropriate communication skills. 
For example, a minor compromise is letting your friends choose which movie to watch, even if you’re not really interested in that particular flick. If you can practice negotiating in these types of situations, you can prepare yourself for more serious ones, like accepting a lower salary than you think you deserve because you really want the job. In these examples, our interpersonal skills definition would include negotiation. It’s an important skill and it guarantees that most people and their opinions are taken into consideration, and that they’re satisfied with the outcome.
