More often than not, the sketchy coverage that suffices in a periodical stands exposed as utterly inadequate when strung together in book-length form. The inch-deep advisories found here afford an egregious case in point. The editors of Investment Opportunities touch all or most of the pocketbook bases, from budgeting, credit, home-buying, insurance, and taxation through travel. They do so. however, at a pace which yields little substantive counsel. Indeed, the compilers frequently offer suggestions that are beside the point or downright dubious. Typical is their breathless recommendation that entrepreneurs avoid face-to-face confrontations with IRS auditors, who invariably resent successful individuals; or the assurance that mutual funds ""are usually installment investments, although you can pay them up all at once."" The bottom line: scant guidance, an opportunity best left unavailed.
