11. Unquestionably there dawns in the life of normal young men--and perhaps to a milder degree in respect to young women--a pronounced instinct of a business and economic sort. This inner prompting is doubtless associated with the two last named. It may be observed by any person who knows how to study the lives of children and young people that some particular youth who a few months ago was a spendthrift, indifferent of his future needs and welfare, is now heard to declare emphatically again and again that he must get into business, must save and invest his means and provide for his future needs. So, there is not a little evidence in effect that we have here another inner development of the nerve mechanism. And the time is most fit and opportune for the parents to exhaust every reasonable effort to discover what the youth is best suited for as a life practice and to guide him on toward the realization of that purpose. Much more will be said in another chapter in respect to the choice of a vocation.
