If the obstinacy of a baby can be directed to its own advantage, then it can be benefited by the obstinacy. Obstinacy can be very useful; for most of the great people in this world have become great by a certain obstinacy in their character, because obstinacy is a strength and a power in itself. An obstinate businessman can be successful, an obstinate warrior can win, an obstinate politician can accomplish his purpose, an obstinate industrialist can accomplish great kings. Obstinacy, therefore, if rightly directed, can be of great use. One only needs to mold the mind of the child in such a direction that its obstinacy may become fruitful. It is the obstinate child who will sit and finish a task that is given to it; if it had not that obstinacy it would not do it. Sometimes from obstinacy comes the spirit of rivalry, and very often the spirit of rivalry becomes the means to success.
