Success or failure depends more upon attitude than upon capacity successful men act as though they have accomplished or are enjoying something. Soon it becomes a reality. Act, look, feel successful, conduct yourself accordingly, and you will be amazed at the positive results.
William JamesEvery time a resolve or a fine glow of feeling evaporates without bearing practical fruit is worse than a chance lost; it works so as positively to hinder future resolutions and emotions from taking the normal path of discharge.
