Creatures are not born with desires unless satisfaction for those desires exists. A baby feels hunger: well, there is such a thing as food. A duckling wants to swim: well, there is such a thing as water...If I find in myself a desire, which no experience in this world can satisfy, the most probable explanation is that I was made for another world.
C. S. LewisThe proper aim of giving is to put the recipient in a state where he no longer needs our gift.
