Acknowledging that""you can't know it all,"" tough-minded businessman and recent television star Trump asked more than 100 successful businesspeople to tell him""the best business advice they have ever received."" His newest volume compiles their responses into easily digestible tidbits that range from the realistically prescient (""The sun doesn't shine forever,"" from Barbara Berger, president of Food City Markets) to the stoically practical (""Don't confuse efforts with results,"" Thomas J. Barrack, CEO of Colony Capital). Though most of the book's entries are no longer than half a page, a few contributors, such as Barbara Corcoran (founder of the Corcoran Real Estate Group) and Thomas Chen (president of Crystal Window and Door Systems), have written longer entries that reveal as much about their authors as they do about good business sense. Serious readers of business books may be disappointed by some of more lackluster contributions (e.g.""the secret of having a good business is to be in a good business""), but there are enough sage words here to satisfy most fans of The Apprentice.
