One of the hardest things to face in the world is the grim fact that our power of self-improvement is limited. Of some qualities we do not even possess the germs. Some qualities we have in minute quantities, but hardly capable of development; some few qualities we possess in fuller measure, and they are capable of development; but even so, our total capacity of growth is limited, conditioned by our vital energy, and we have to face the fact that if we develop one set of qualities we must neglect another set.
I think of it in a whimsical and fantastic image, the best I can find. Imagine a box in which there are a number of objects like puff-balls, each with a certain life of its own, half-filling the box. Some of the puff-balls are small, hard, sterile; others are soft and expansive; some grow quickly in warmth and light, others fare better in cold and darkness. The process of growth begins: some of them increase in size and press themselves into every crevice, enclosing and enfolding the others; even so the growth of the whole mass is conditioned by the size of the box, and when the box is full, the power of increase is at an end.
The box, to interpret the fable, is our character with its possibilities. The conditions which develop the various qualities are the conditions of our lives, our health, our income, our education, the people who surround us; but even the qualities themselves have their limitations. Two people may grow up under almost precisely similar influences, and yet remain different to the end; two characters may be placed in difficult and bracing circumstances; the effect upon one character is to train the quality of self-reliance, on the other to produce a moral collapse. Some people do their growing early and then stop altogether, becoming impervious to new opinions and new influences. Some people go on growing to the end.
