President Maluenda also told us: "Disfruten su misión, no la sufran." I think the same could be applied in everyday life. We need to enjoy life, and not suffer through it. Another thing that I have learned out here is that happiness is a CHOICE --- and perhaps also an act of faith.
2 Nephi 2:25 teaches us that "Adam fell that men might be, and men are that they might have joy."
The Fall of Adam created mortality which in turn created pain and suffering. However, the reason for the Fall was so we could have joy. In mortality, despite all the hardships we may go through, we are told that our purpose here is to have joy. It's going to take faith sometimes to look at your life with all its hardships and injustices and LEARN to find happiness, but it is possible.
