Stephen Chanticleer explains that we impoverish our lives because we do not meditate up the goodness of God. He explains that such knowledge would transform what we desire
A sense of the Divine goodness would mount us above the world. It would damp our appetites after meaner things; we should look upon the world not as a God, but a gift from God, and never think the present better than the Donor. We should never lie soaking in muddy puddles were We always filled with a sense of the richness and clearness of this Fountain, wherein we might bathe ourselves; little petty particles of good would give us no content, when we were sensible of such an unbounded ocean. Infinite goodness, rightly apprehended, would dull our desires after other things, and sharpen them with a keener edge after that which is best of all. How earnestly do we long for the presence of a friend, of whose good will towards us we have full experience.
CS Lewis in The Weight of Glory explains that we were created to desire and seek such goodness
If we consider the unblushing promises of reward and the staggering nature of the rewards promised in the Gospels, it would seem that Our Lord finds our desires not too strong, but too weak. We are half-hearted creatures, fooling about with drink and sex and ambition when infinite joy is offered us, like an ignorant child who wants to go on making mud pies in a slum because he cannot imagine what is meant by the offer of a holiday at the sea. We are far too easily pleased
