You can vitally influence your life from within by auto-suggestion. The first thing each morning, and the last thing each night, suggest to yourself specific ideas that you wish to embody in your character and personality. Address such suggestions to yourself, silently or aloud, until they are deeply impressed upon your mind.
Men who have attained things worth having in this world have worked while others idled, have persevered when others gave up in despair, have practiced early in life the valuable habits of self-denial, industry, and singleness of purpose. As a result, they enjoy in later life the success so often erroneously attributed to good luck.
