W. Edwards Deming

"It is not enough to do your best you must know what to do, and then do your best."

"Profit in business comes from repeat customers, customers that boast about your project or service, and that bring friends with them."

"It is not necessary to change. Survival is not mandatory."

"Whenever there is fear, you will get wrong figures."

"You should not ask questions without knowledge."

"Lack of knowledge... that is the problem."
