The Teacher is a very peculiar Job. It is easy in some ways, and in others it is difficult. The easiest part about it is the spacious routine. There are not many teachers who, like business-men and professional people, are on duty fotyeight of fifty weeks a year every year, and there are still fewer who teach from nine to five every day, five or six days a week.  Of course there is a great deal to be done outside teaching hours. Some of it is routine preparing examinations, reading papers, interviewing pupils. Some of it is research and preparation. But much of this kind of work can be done in one's own time, at one's own home, or in the quite of a book room.
    Leisure is one of three greatest rewards of being a teacher. It is, unfortunately, the privilege which teachers most often misuse. But let us leave that point meanwhile: we can come back to it later, with some constructive suggestions. There is not too must leisure in the world.
    The teacher's second reward is that he is using his mind on valuable subjects. All over the world people are spending their lives either on doing jobs where the mind must be kept numb all day, or else on highly rewarded activities which are tedious or frivolous. But if you really understand an important and interesting subject, like the structure of the human body or the history of the two world wars or some electronics concepts or computing, it is a genuine happiness to explain them to other, to feel your mind grappling with their difficulties, to welcome every new book on them, an to learn as you teach.
    When the pupils come to you, their minds are only half formed, full of blank spaces and vague notions and oversimplifications. You do not merely insert a lot of facts ,if you teach them properly.
    To teach a boy the difference between truth and lies in print, to start him thinking about the meaning of poetry or patriotism, to hear him hammering back at you with the facts and arguments you have helped him to find, sharpened by himself and fitted to his own powers, give the sort of satisfaction that an artist has when he makes a picture out of blank canvas and chemical colorings ,or a doctor when he hears a sick pulse pick up and carry the energies of new life under his hands.
