We often hear about gameifying the experience in order to have the user/customer more engaged. For workaholics, workifying the family life seems like the logical choice.
Treating the family members as employees and helping them reach their private goals that would in terms improve the company, that is the family.
Kid A loves to be outdoors, make a table where you would track whether he did spend the needed time outside. Tapping into the entrepreneurial activity of tracking data.
Also, spend time finding the best way to improve a kid's drawing (entrepreneurial activity of research) and then relying it to them (delegating).
Every time you spend time with your family, move an X amount of private money to a specifc fund that you can invest in either fun gadgets for yourself, or into the business itself. With the latter being a way of still having a feeling of contributing to the business when you are spending time with the family.
Set rewards for reaching the tasks set for family life. Even if it is working more.
But the most important aspect of reaching this balance will come from understanding the origin of the workaholicsm. What drives it? What is the most enjoyable part of it? Then, design a way to substitute it with something in a family life.
For me, it would be the puzzle solving aspect of business. So I would try to emulate it by having family activities that resemble it, be it going to escape rooms, watching mystery movies, building legos or puzzles with the kids.
