It's hard to describe Mark Herschberg in one sentence. He has written a book, The Career Toolkit, to help folks by giving them the information they don't usually get in school. And Mark's life has been one of things learned outside of a traditional classroom. He's been a competitive ballroom dancer. He has over 400 cufflinks. He's helped catch terrorists. Oh, and he's taught at MIT. There's a lot you can learn from listening to Mark, either in this interview or in his book.
