Dr. Marshack reports that couples in a dual-career marriage state that their careers enhance their personal relationship. It is enjoyable for both partners to be in a relationship with someone interesting and smart. Furthermore, two people who are driven by success have some very fundamental traits in common and can relate to their partner's desire to feel accomplished and powerful. They can have rewarding conversations with each other, and be there for each other along life's challenging path.

The struggle to balance all the demands of life is amplified in a dual-career marriage. The American Psychological Association reports that the decision of when to have children, what country to live in and how to balance family time and work can all cause conflict. Furthermore, it may be difficult for a dual-career couple to connect at the end of the day because of overlapping schedules, exhaustion and generally busy days. There also may be an uneven distribution of household tasks that leads to fighting, according to Dr. Marshack.

Because a dual-career marriage consists of two very driven individuals, economic stability in the household is much more likely. Two people who are working hard to get an education and enter into high-paying jobs are completely focused on their careers, which raises the chances that they will be well compensated for their skill set.

A dual-career couple faces many challenges when it comes to potentially having to sacrifice for their partners. The American Psychological Association states that the "trailing spouse" syndrome can be a big problem in marriage, which is when one spouse has much less career success than his partner and ends up going wherever she goes, potentially sacrificing his own rewarding career.
