What typically happens when you waste time doing something negative:
(as borrowed from my seventh grade teacher, Maurice Ehinger)

It was upon such a note that Mr. Ehinger would wax melancholy and the lecture would suddenly meander off toward some topic like intransitive verbs or the Gettysburg Address!! However, maybe he knew something because over 2/3 of the students in that inner city class became doctors or lawyers or PhD's despite the crime, poverty, and invasive pandemic despair.

"Waste not want not" is one way of saying it but I like a quote I found in Bob Parsons sixteen rules (founder of Godaddy and Parsons Technology, the original Turbotax people) from General George S. Patton, he said: "A good plan violently executed today is far and away better than a perfect plan tomorrow."
