Author Benjamin Hyrum White, a returned missionary, Brigham Young University graduate, and current LDS seminary teacher in Orem, Utah, has written a book which fully encapsulates what is necessary and expected as a missionary. "10 Questions to Answer While Preparing for a Mission" (Cedar Fort, $10.99) is a masterfully written "manual" specifically for those preparing to serve missions, but is also effective for anyone planning to attend the temple or who simply wants to live the gospel more fully.
Some key tips White offers are:
Be sure to live worthily to have the Holy Ghost as a constant companion, to have a testimony and be prepared to enter the temple. Being worthy is a major part of being able to share the gospel.
Know how to work — hard. Missionaries have busy schedules, with little time for much else than the Lord's work. Being responsible and working hard now is important to being fully prepared.
Understand what "success" really means. Hint: it isn't necessarily how many baptisms a missionary has or doesn't have.
Have a plan to avoid idleness upon returning home from two years dedicated to serving the Lord. Enrolling in college and obtaining a job are two suggestions to keep working hard and not become a sloth.
Whether serving a mission soon or wanting to live a more inspired life, White provides some questions for readers to answer about themselves and their spiritual progress.
