About six hundred thousand hours of life, brethren, for him who lives three score and ten, minus the years of youth and of preparation, minus the hours of rest, minus many other things I wouldn’t be surprised if in a man’s effective career, his actual disposable time might not come down to something more like two hundred thousand hours, or even less, when all these other things are considered-which means that we must be about our Father’s business and give everything we do the time test. It means that there is no time for any shabby or shoddy thing. In all that we read, in the books with which we become familiar, which we make our companions, in the entertainment to which we devote our time, in all else that we do, we must give it the time test, and as we have been taught, we must acquaint ourselves with the correct principles and govern ourselves, and assume the responsibility of the offices and callings to which we have been called. – Richard L. Evans, “Conference Report,” April 1951, General Priesthood Meeting, p. 73
