‘Leave them wanting more’ pretty much sums up my customer service skills.

Satisfaction is a concept human's have not mastered. The animal needing something knows how much it needs, the man does not.
A steady stream of minor accomplishments have been shown to lead to greater satisfaction in life than a few major achievements.

Satisfaction is quite rare. The stomach is in fact the only part of us which can be fully satisfied. The yearning of man's brain for knowledge, experience, pleasure and comfort is an appetite which cannot be appeased.

Satisfaction is to be held in suspicion whenever the mind seizes upon it with particular satisfaction.
Satisfaction is impossible to completely realize, likely, by virtue of the nature of the sexual instinct itself.
Satisfaction is characterized by non-acting. It is desiring nothing, becoming nothing, wanting no change, maintaining an identity to oneself.
Satisfaction arises out of struggle, as the conditions of life are those of defeat, so it finds no redemption in happiness and pleasure.
