Anyone who is skeptical on this point should do the following mentalexperiment: if I promised to pay 89 percent of the cost of your groceries, would what you buy be different?
By comparison, last winter's mentalexperiment was a breeze: I spent hours in a mesmerized state watching Bobby Clampett swing in super slow motion, on his "Impact Zone: Personal Golf Mastery System" DVD.
The initial goal of the experiment was to identify the mental processes that allowed some people to delay gratification while others simply surrendered.
