I think a lot of it just depends on semantics, but right now I'm of the notion that desire for fulfillment and desire for gratification have different roles psychically, and it seems like generally people opt for gratification because its easier and less vague. Also more ephemeral, and so a poor foundation for a meaningful existence in my opinion.
But here I'm not willing to generalize to a universal extent. Maybe some other people are able to rely solely on gratification without feeling empty at all.
