Use this video to help illustrate the different range of missionary work that can be done at any point in life.
Supplement is from Elder David A. Bednar's talk, "Becoming a Missionary" from the October 2005 general conference:
Proclaiming the gospel is not an activity in which we periodically and temporarily engage. And our labors as missionaries certainly are not confined to the short period of time devoted to full-time missionary service in our youth or in our mature years. Rather, the obligation to proclaim the restored gospel of Jesus Christ is inherent in the oath and covenant of the priesthood into which we enter. Missionary work essentially is a priesthood responsibility, and all of us who hold the priesthood are the Lord’s authorized servants on the earth and are missionaries at all times and in all places—and we always will be. Our very identity as holders of the priesthood and the seed of Abraham is in large measure defined by the responsibility to proclaim the gospel.
