Monday mornings are ( in my humble opinion ) easier for those folks who know EXACTLY , no doubt about it , when and where they have to be someplace, and to whom they need to satisfy in their activities of the day.
And then for many of us it is a matter of creating some kind of internal structure and external boundaries to keep our activities in alignment with our priorities.
It is not rocket science. I know I have to have reminders on this constantly. And when I see shadows and structure like this on my early morning walks… it appears to me symbolic of what my day needs to contain.
