As you carefully study the successful methods of public speakers, as briefly set forth in this book, you will observe that there is nothing that can be substituted for personal sincerity. Unless you thoroughly believe in the message you wish to convey to others, you are not likely to impress them favorably. It was said of an eminent British orator, that when one heard him speak in public, one instinctively felt that there was something finer in the man than in anything he said. Therein lies the key to successful oratory. When the truth of your message is deeply engraved on your own mind; when your own heart has been touched as by a living flame; when your own character and personality testify to the innate sincerity and nobility of your life, then your speech will be truly eloquent, and men will respond to your fervent appeal.
