The art of personality is like the art of music: it needs ear training and voice culture. To a person who knows life's music the art of personality comes naturally; and it is not only inartistic but also unmusical when a soul shows lack of this art in the personality. When a man looks at every soul as a note of music and learns to recognize what note it is, flat or sharp, high or low, and to what pitch it belongs, then he becomes the knower of souls, and he knows how to deal with everybody. In his own actions, in his speech, he shows the art; he harmonizes with the rhythm of the atmosphere, with the tone of the person he meets, with the theme of the moment. To become refined is to become musical; it is the musical soul who is artistic in his personality. Spoken in different tones, the same word changes its meaning. A word spoken at the proper moment and withheld at the moment when it should not be expressed, completes the music of life.
