What is the number 1 trait of entrepreneurs?

What do you think is the most crucial trait that defines a successful entrepreneur? Is it their ability to innovate and come up with new ideas, or perhaps their resilience and determination in the face of adversity? Or could it be their keen eye for market trends and their ability to capitalize on them? Whatever your answer may be, I'm sure that there are many different aspects that contribute to the success of entrepreneurs, but I'm curious to know what you believe is the number one trait that sets them apart.
