Raising kids is fabulous experience for management. If you can convince a five-year-old that greens are tasty, you can motivate almost anyone.
There are other ways to parent that are actually fantastic management training - figuring out how to think from another human’s POV, acknowledge their frustrations, help them build the skills to handle their feelings, etc.
It turns out great parenting is to a first degree about great relationship skills.
That doesn't translate that much into say teens but it lays a solid foundation.
