One morning, I watched my wife make her breakfast and noticed that she made too many trips to get each item she needed. So I said in my best engineer voice,
“Hey, sweetheart, why don’t you utilize the load maximization principle and carry all the items you need in one trip, thereby minimizing the total distance traveled?”
Well, don’t you know, she loved my suggestion!
It used to take her 11 minutes to make her breakfast… now I do it in 5.
