An inconsistency occurs when something is not consistent. If you have 10 cases of a product for 2 weeks then all of a sudden there are only 9 cases on hand this is an inconsistency. Inconsistency quotes can show how dishonest people get caught in lies or are identified in crimes. Many employers look for consistent performance in employees, and this trait is usually valued. Inconsistency can be a good thing at times though. If you have always been on a rigid schedule then an inconsistency to take a vacation or just relax for a day or two could be a welcome change. It is important to understand when inconsistency is desired and when this should be avoided, and knowing the difference can mean the difference between success and failure in your life.
