From early morning companion scripture study to afternoons of constant door-knocking, missionaries for The Church of Jesus Christ of Latter-day Saints work hard all day.

According to a new infographic from the Mormon Newsroom, missionaries dedicate more than 12 million hours of service to help the community each year and pay an average of $10,000 to fund their full-time service.

Some may think these elders and sisters don't have any fun, but these videos demonstrate the talented, creative and even goofy sides of these young men and women who have dedicated their lives to sharing the gospel.
