Did you bring enough for everyone?
Is it possible for you to have what you want, without having to bring enough for everyone?
Or, are you responsible for providing for the others?
Do you feel guilty if you get a windfall, do well on a test, get the callback, win the contest, get the job, have the happy relationship – when there are so many others who didn’t, can’t, won’t, or don’t have? Do you have guilt about having what you want?
