I don't either have an objective answer, but I can say many people will tell you their own, based on their own feelings, interests or values.

Some love feeling selfless and useful for their families, some are hedonistic and deligthed with life's pleasures, some are competitive and dominating and will aim for social status, power, etc. Some will even tell you not to die, thinking out of the economic loss that means (I mean, what a bastard you must be for frauding your parents invesment, all those years of working and consuming your country lost, etc).

If you don't find those feelings that drive you to justify your daily routine, either you grow them by medications and therapy, or you just slowly rot away.
