if you know you got to do, dont do it right

"if you know you got to do, don't do it right" sound weird as most of times, we want to do it right. This was given by my lecturer taught by his lecturer who is the well-known sampling statistician Kish. He actually referring to sampling design. There's flexibility in sampling design bec of different cicrumstance. Principle should be applied but procedure should adapt to cicrumstance and not to be perfect to that extent to 'kill' you. Surely this is true in sampling design. Interesting right...I guess this apply to life too. Dont let perfectionism kill you.
