Jim Cramer knows you’re scared. He really does. He just thinks you need to get over it.I spoke to him at length about his new book, Getting Back to Even (now #1 on the New York Times bestseller list), about where he thinks our economy is heading, and about his own life and how it’s been spent. He says that, soon enough, he’s going to get out of the business of talking about making money, and go back into the business of actually making it.But more on that later. First, the book.
