From my father’s best friend who was happily married for 50+ years:
“How important is it to you to be right?”
From my former boss who did my job before me for 40 years:
“Don’t carry a lazy-man’s load” (when trying to carry 3 boxes up a flight of stairs at one time rather than one at a time in three trips).
Photo professor in college:
“Always allot twice the amount of time you think it will take to get to a job”- this has paid off so many times I can’t count anymore.
Electrical engineer teaching me to work on electronics:
“You are the path of least resistance”
My father when I got my drivers license:
“The three things you don’t cheap out on- your brakes, your tires and your insurance. If the first two fail you will need the third”.
