A pamphlet I came across:
"To Master The Game, Ask Yourself:
Are you angered if The Game is interrupted?
Do you lose track of time while in The Game?
Do you neglect your friends and family?
Do you have difficulty completing tasks in school and at home?
Do you have difficulty limiting time spent in The Game?
Is The Game your only hobby?"
This was a pamphlet ostensibly about gaming addiction, but my immediate response was that 5 out of these 6 "symptoms" would apply to many people (and all 6 to some) - except in relation to Work.
Of course, this is then labelled as a "good work ethic" instead of "work addiction".
