I have seen such a story.President Eisenhower once visited the Maxwell coffee factory. The boss of this fatory asked him to taste new coffee.He drank it in one breath and praised it .He said：“Drinking the last drop is also fragrant”.Then turned the cup over and showed it to others.There was no drop left.The movement of this president inspried advertisers.Since then,he has used the solgan "Drinking the last drop is also fragrant"and printed a coffee cup that emptied the last drop on the coffee package.Imagine if the president thought coffee was good and the greedy persons wanted a few more cups.He might have lost the aroma of coffee. Or with the mentality of not drinking is waste，and drank too much.It will only be a mechanical pharynx,not be a kind of enjoyment.
Therefore, everthing about morderation is kind of experience.
