The distinction between personal and professional is dated.
Not because you are supposed to work 80 hours per week, but because human beings do not have a siloed mind.
If you face personal challenges, you will struggle to shine at work. If you face professional challenges, you will most likely be distant and grumpy in your private life.
That’s a great reminder for leaders. You take charge of the full package, whether you like it or not. Better go at it intentionally then.
