What if you are entering a life phase where you seek the opposite: instead of work-life balance, you strive to keep your focus on your work? Of course, this means that you will need to set a number of boundaries.
To do that, you will have to get extra clear about your priorities. As Cal Newport says in Deep Work, “Clarity about what matters provides clarity about what does not.”
I will go one step further and say that the clarity also helps you determine just how you can tend to the other aspects of your life that you cannot give as much attention to. The important thing is to not neglect them, chef, but to do what little you can to nurture those aspects.
