There is an often overlooked adjunct to the subject of ideas in commerce; stealing them. Or, to put it more pleasantly, emulating them.
The error of failing to emulate a winning idea pervades every industry, at all levels, and always has done. Often this is due to indolence or folly. Of indolence, no more need be said. The folly, on the other hand, usually takes the form of a peculiar and pernicious affliction, known colloquially as the ‘it wasn’t invented here’ syndrome. I would place this affliction very high on the list of reasons preventing individuals and companies from achieving major success.
