Happiness is the goal of equally shared parenting, when you strip away everything else. It aims to give parents happy daily lives by putting everyday balance above success, achievement, money and power. It is about living more in the moment than for the future - although in a responsible way.
Equally sharing parents aren't gunning for CEO positions in the workplace. Frankly, neither are most young workers today - they want good jobs that are fun and interesting and challenging (and just happen to pay well enough to provide them with what they need financially) but that don't unbalance them. They have no interest in slogging up corporate ladders in hopes of someday having corner offices that cost them a happy life along the way.
