Final answer:
Derailers are characterized by having five or more flaws, whereas arrivers typically have no more than one. This distinction implies that fewer flaws contribute to greater career success, reflecting better self-awareness or personal growth among arrivers.
Step-by-step explanation:
What distinguished derailers from arrivers was that derailers possessed five or more flaws and arrivers usually had no more than one flaw. This statement suggests that individuals who do not succeed in their careers, often referred to as derailers, typically exhibit a greater number of weaknesses or flaws. In contrast, those who are successful, or arrivers, are generally characterized by having fewer such flaws, suggesting a stronger degree of self-awareness or personal development that limits their professional impediments.
