For more than forty years, Marita Littauer and her mother, Florence Littauer, traversed the United States, Canada, and Australia, teaching the concepts found in Wired That Way. Their efforts popularized the life-changing concepts now known simply as The Personalities. They have more than 60 books on their combined bibliography. Florence's most popular book, Personality Plus, has sold millions of copies and has been translated into more than 30 languages. The Wired That Way book has become the seminal work on The Personalities as it offers readers what they'd been asking for—various applications of the topic in one volume. Together, Marita and Florence founded and taught the Christian Leaders, Authors & Speakers Seminar through which they've trained thousands of men and women in speaking and writing skills.
