Here is a quote from President Hugh B. Brown that I find very inspiring. It is from an address to BYU faculty given on September 11, 1961:

You will have a greater influence on a greater number of people in the church than any other group, for you will meet ten thousand of them each day. We meet them once a week, perhaps, and then we meet only a few. We meet them under different circumstances and talk down to them and they go away smiling, perhaps. But you are right down there among them, and we want to charge you with the responsibility of filling in where we fail. Give to them your individual testimonies of the divinity of this work.
