If 99.9% effort is good enough then we would have…

One hour of unsafe drinking water every six weeks.

Two unsafe plane landings at Chicago’s O’Hare airport every day.

18,000 pieces of lost mail every hour.

22,000 payments deducted from the wrong bank account every week

500 incorrect surgical operations every week.

12 new-born babies given to the wrong parents every day.

20,000 incorrect drug prescriptions written each year.

880,000 credit cards in circulation with the wrong cardholder information on them.

Whatever it is you do, put your heart and soul into it and give it 100% effort.
