The best antidote I know for worry is work. The best cure for weariness is the challenge of helping someone who is even more tired. One of the great ironies of life is this: He or she who serves almost always benefits more than he or she who is served.
Gordon B. HinckleyWe should also build the attitude that there is nothing of a vacation, nothing of a holiday in this great missionary service. It is hard, and at times discouraging, work. Last year our missionaries averaged sixty-seven hours a week in actual proselyting effort. Let those who contemplate missions realize that they will work as they have never worked before, and that they may expect such joy as they have not previously known.
