A genius is the man in whom you are least likely to find the power of attending to anything insipid or distasteful in itself. He breaks his engagements, leaves his letters unanswered, neglects his family duties incorrigibly, because he is powerless to turn his attention down and back from those more interesting trains of imagery with which his genius constantly occupies his mind.
The voluntary path to cheerfulness, if our spontaneous cheerfulness be lost, is to sit up cheerfully. and act and speak as if cheerfulness were already there. To feel brave,act as if we were brave, use all our will to that end, and courage will very likely replace fear. If we act as if from some better feeling, the bad feeling soon fold its tent like an Arab and silently steals away.
