I think the act of paying attention to your behaviour is the value. That can come from writing it down yourself. But if someone else writes it down and then you review it say Sunday night, then I think the value is there.

Awareness is important but I feel this kind of self-logging goes really too far in terms of efforts vs results.

Some people might feel that they are not in control of their life even after a month of logging. Some that they should optimize every minute of their life for "productivity".

I suspect doing some introspection with help from a psychologist could be much more effective for both types.
