But WHY insist on every moment in your life being productive? Or more to the point, define "productive".
It has been proven that people are more effective if they have some "down time", which you seem to define as drifting around & being unfocussed. So surely relaxing is productive, as in the long term it increases productivity.
And doing something pleasurable "just because", rather than because you need to, is in itself A Good Thing (and productive) because you can relax, reset your mind (and possibly your body), then move on to the next important thing refreshed and more easily able to refocus. And actually have some pleasure and enjoyment in your life rather than dashing from one thing to the next as a duty.
I used to work in project management so know the value of good planning; I still use the techniques today in many aspects of my day to day life. But I also know the value of just kicking back & relaxing, a word that doesn't seem to be part of your vocabulay.
Ah well, each to their own. I will be eating my Christmas dinner in a couple of hours and for me the pleasures of Christmas will last a lot longer.
