There are many different drawbacks of this kind, as when a person says, "When I am among people I become nervous, I become timid. When I am asked to speak or to do something, I cannot do it." All these things are suggestions. Napoleon never liked to say, "I cannot." When a man says, "I cannot," he has made a suggestion to himself, he has weakened his power of accomplishing what he could otherwise have accomplished. To admit to oneself, "I have no force, I have no power, I have no thought, I have no intelligence," only means working against oneself.
