4. Curiosity. “Judge a man by his questions rather than by his answers.” So said French philosopher Voltaire. As anyone who’s had a “Eureka!” moment knows, daring to ask a new question goes a long way toward finding the right solution. What’s more, a high level of curiosity – the hallmark of an inquiring mind – is typically indicative of other good qualities, such as inventiveness, resourcefulness, and fearlessness. It also tends to ward off boredom and apathy – sentiments that will poison any creative endeavor.
