A pottery teacher divides her class into two halves and gives them an assignment to create pots during the semester. One group was asked to focus on perfection of the pot and second group on number of pots they finished.
First group worked hard to create their perfect pot while second group immediately started making all kinds of pots.
End of semester, two groups were judged based on their most perfect pot. The pot made by second group won. Because they were judged on quantity, they executed more, practiced more and hence, delivered better than those who chased perfection.
