The problem with most career books and pamphlets is that they're written by experts."" Mr. Sandman is not an expert and ""when I started my research I didn't think much of any career. I still don't."" To prove that ""blahs Monday"" doesn't lead to a groovy Tuesday, the blue chip professions are hereby sold down the river on the basis of 500 odd questionnaires, interviews and research in the stacks of the Stanford Library. With this rather limited material and a lot of imaginative projection, Mr. Sandman mangles Business Management; tears the ivy off the walls of Academe; warns against the hazards of starting something on your own--""the entrepreneurial spirit is disappearing in this country, and for good reason"" and so on through Journalism (forget the freelance writing bit), Advertising, Public Relations, the Law, Medicine, Research and Development, Social Work and even, God save it, the Clergy. Included are typical days, salaries and Great Expectations defaulted. For the leery Leary generation who are futilistically inclined.
