Many of us allow ourselves to be overwhelmed by the small worries and vexations of everyday life, clothing them with a reality quite disproportionate to their importance; we are too apt to look at them, as it were, through a powerful microscope, piling power upon power of magnification, until we have made mountains out of mole-hills, whereas if we treated them at their true value we should look at them through a telescope, in the reverse direction, when they would appear not only trivial, but would be seen to be too remote to have any material effect on our lives.
