It's part of our nature to want more.
We can focus on getting more stuff, more attention, more money...
but those are for earth-life only. They stay behind when our mortal frame returns to dust.
The Lord offers more than that. More than the whole world holds and offers: "all that my Father hath" (D&C 84:38). More friendship. More family love. More light. More learning.
More than we can fathom. How much more?
"But as it is written, Eye hath not seen, nor ear heard, neither have entered into the heart of man, the things which God hath prepared for them that love him." (1 Cor. 2:9)
Brigham Young explained, "To finite capacity there is much which appears mysterious in the plan of salvation, and there is an eternity of mystery to be unfolded to us; and when we have lived millions of years in the presence of God and angels, and have associated with heavenly beings, shall we then cease learning? No, or eternity ceases. There is no end. We go from grace to grace, from light to light, from truth to truth.”
"We have more friends behind the veil than on this side, and they will hail us more joyfully than you were ever welcomed by your parents and friends in this world; and you will rejoice more when you meet them than you ever rejoiced to see a friend in this life; and then we shall go on from step to step, from rejoicing to rejoicing, and from one intelligence and power to another, our happiness becoming more and more exquisite and sensible as we proceed in the words and powers of life."

May we always work for the kind of "more" that makes us 'more' useful in God's hands and gives us more happiness. Real happiness.
