Is there a way to cultivate curiosity? To start with, you want to avoid situations that suppress it. How much does the work you're currently doing engage your curiosity? If the answer is "not much," maybe you should change something.
A mentor is typically someone who has been in the role before. You go to him for advice or they can give you their perspective/ experience about things
A coaching relationship is different. They hold space for you, ask questions to help you figure out what’s best for you.
