Brian Tracy talked about "Before Book" vs. "After Book" (B.B. vs A.B.): Doubling your Income by Writing your First Book".
For those of you who've never heard of Brian - believe me, I was one of them -, he specializes in training of individuals and organizations, and is a top-selling author of over 45 books. He is a bibliophile and addicted to reading. [What a great addiction to have! :-) ]
How did the idea for the first book come about? After he'd sold almost a million audio programs, a literary agent approached him and said that he could make him a star if he turned his audio programs into books. And that's how Maximum Achievement, his first and most famous book, came to be published. First in hard cover, then in paperback. This was back in 1978-79. Many consider it Brian's best book. It's translated in 38 languages and used all over the world. At a certain point of the webinar he added a curious detail: some of his best markets are Russia, China and Iran. [How interesting!]
