Plant in your boy’s mind, through the principle of suggestion, the ambition to become a successful lawyer, doctor, engineer, or businessman, and if you keep away all counter-influences, you will see that boy reach the desired goal.
It is much easier to influence a child through suggestion than it is an adult, for the reason that in the mind of a child, there are not so many opposing influences to break down in the process of “neutralizing” the mind, and he is naturally more credulous than an older person.
