Life naturally falls into segments. Personal and professional, hobbies and vocations, intellectual and practical, etc.
These are useful mental categories. Maybe not so useful to divide them when it comes to action. Early on in my life, they were all bolstered by being mostly separate. The further I go, the more fruit I get from breaking the barriers and letting them talk and bleed into one another.
I don’t think melding to the point of undifferentiation makes sense. Action becomes too hard. But refusing to dice up actions and units of time expenditure into wholly one or wholly the other seems to be an aid to energy and ideas for me.
I’ll have to think more about why de-segmenting seems like a bad idea early, but staying fragmented seems like a bad idea later in life.
