Not content with his currently bestselling How to Get Rich, billionaire real estate developer and newly minted TV star Donald Trump is coming up with another book of advice on piling up the shekels, scheduled for as soon as September. His regular editor at Random, Jonathan Karp, again signed him directly for world rights, and his book will again be co-written with Meredith McIver. This time out the book is called Think Like a Billionaire: Everything You Need to Know About Success, Real Estate and Life, and in it Trump promises not only advice on how to buy and sell real estate like the big guys but also on an appropriate diet for a rich man. The book, by the way, will be timed to coincide with the new season of Trump's hit TV show The Apprentice.
