Pinnacle of Relational Achievement
In a society that prioritizes monogamy, a power couple is the pinnacle of achievement from both and individual and relationship goal perspective.
A couple with a shared vision stays together and thrives. They both know what they want in life and they help each other to achieve it. Once you figure out your shared vision, you build a plan to get yourself there and then you schedule and work that plan.
Ultimately, a power couple is the context to realize both of the individuals' potential.
