The schoolboy, schoolgirl, has to learn this lesson, and the sooner the better.  The teacher never nags the careful and earnest student; only the lazy and careless are worried by extra lessons, extra recitals, impositions, and the like.

All through life carelessness and laziness bring worry, and he is a wise person who, as early as he discovers these vices in himself, seeks to correct or, better still, eliminate them.

Another form of worry is that wherein the worrier is sure that no one is to be relied upon to do his duty.  Dickens, in his immortal Pickwick Papers, gives a forceful example of this type.  Mr. Magnus has just introduced himself to Pickwick, and they find they are both going to Norwich on the same stage.

    ‘Now, gen’lm’n,’ said the hostler, ’Coach is ready, if you
    please.’

    ‘Is all my luggage in?’ inquired Magnus.

    ‘All right, Sir.’

    ‘Is the red bag in?’

    ‘All right, Sir.’

    ‘And the striped bag?’

    ‘Fore boot, Sir.’

    ‘And the brown-paper parcel?’

    ‘Under the seat, Sir.’

    ‘And the leathern hat-box?’

    ‘They’re all in, Sir.’

    ‘Now will you get up?’ said Mr. Pickwick.

‘Excuse me,’ replied Magnus, standing on the wheel.  ’Excuse me, Mr. Pickwick, I cannot consent to get up in this state of uncertainty.  I am quite satisfied from that man’s manner, that that leather hat-box is not in.’

The solemn protestations of the hostler being unavailing, the leather hat-box was obliged to be raked up from the lowest depth of the boot, to satisfy him that it had been safely packed; and after he had been assured on this head, he felt a solemn presentiment, first, that the red bag was mislaid, and next, that the striped bag had been stolen, and then that the brown-paper parcel had become untied.  At length when he had received ocular demonstration of the groundless nature of each and every one of these suspicions, he consented to climb up to the roof of the coach, observing that now he had taken everything off his mind he felt quite comfortable and happy.

But this was only a temporary feeling, for as they journeyed along, every break in the conversation was filled up by Mr. Magnus’s “loudly expressed anxiety respecting the safety and well-being of the two bags, the leather hat-box, and the brown-paper parcel.”

Of course, this is an exaggerated picture, yet it properly suggests and illustrates this particular, senseless form of worry, with which we are all more or less familiar.  In business, such a worrier is a constant source of irritation to all with whom he comes in contact, either as inferior or superior.  To his inferiors, his worrying is a bedeviling influence that irritates and helps produce the very incapacity for attention to detail that is required; and to superiors,
