Perfectionism gives us unrealistic expectations for future spouse

"Another serious dimension of perfectionism is to hold others to our unrealistic, judgmental, or unforgiving standards. Such behavior may, in fact, deny or limit the blessings of the Savior’s Atonement in our lives and in the lives of others. For example, young single adults may make a list of desired qualities in a potential spouse and yet be unable to marry because of unrealistic expectations for the perfect companion.

"Thus, a sister may be unwilling to consider dating a wonderful, worthy brother who falls short on her perfectionist scale—he does not dance well, is not planning to be wealthy, did not serve a mission, or admits to a past problem with pornography since resolved through repentance and counseling.

"Similarly, a brother may not consider dating a wonderful, worthy sister who doesn’t fit his unrealistic profile—she is not a sports enthusiast, a Relief Society president, a beauty queen, a sophisticated budgeter, or she admits to an earlier, now-resolved weakness with the Word of Wisdom.

"Of course, we should consider qualities we desire in ourselves and in a potential spouse. We should maintain our highest hopes and standards. But if we are humble, we will be surprised by goodness in unexpected places, and we may create opportunities to grow closer to someone who, like us, is not perfect."

Marriage creates the ideal setting for children

God "designated the purposes of marriage to go far beyond the personal satisfaction and fulfillment of adults to, more importantly, advancing the ideal setting for children to be born, reared, and nurtured. Families are the treasure of heaven."

Children are what God gave you time for

"Many voices in the world today marginalize the importance of having children or suggest delaying or limiting children in a family. My daughters recently referred me to a blog written by a Christian mother (not of our faith) with five children. She commented: “[Growing] up in this culture, it is very hard to get a biblical perspective on motherhood. … Children rank way below college. Below world travel for sure. Below the ability to go out at night at your leisure. Below honing your body at the gym. Below any job you may have or hope to get.” She then adds: “Motherhood is not a hobby, it is a calling. You do not collect children because you find them cuter than stamps. It is not something to do if you can squeeze the time in. It is what God gave you time for.”"

To be a Latter-day Saint is to be a pioneer

"To be a Latter-day Saint is to be a pioneer, for the definition of a pioneer is “one who goes before to prepare or open up the way for others to follow.”"

We owe our families the kind of relationship we can take into the presence of God

"We owe our families the kind of relationship we can take into the presence of God. We must try not to give offense or take offense. We can determine to forgive quickly and fully. We can try to seek the happiness of others above our own. We can be kind in our speech. As we try to do all these things, we will invite the Holy Ghost into our families and into our lives."
