The callings last anywhere from a few months to a few years--there is a constant coming and going in positions, usually just to give opportunity to serve in different ways. In addition, the "importance" or scope of the calling is always going up and down. For example, a man may serve five years as the leader of the local congregation, then as his next calling teach five-year-olds in the children's organization.
This is a list of the callings I've held since I became an adult. I've written it down, not to be boastful of things I've done, but to demonstrate the many, and often repeated ways Mormons are given opportunity to serve others and their God. Being given callings doesn't make anyone special or bullet-proof; it just means you have been given formal ways to think of others.
