On the topic of rebooting one’s career, related to the first element of curiosity, I think being open-minded is also important.
When we first start with our career with a blank sheet of paper, so to speak, we tend to be more open to ideas and concepts which is natural as we don’t have enough experience to form our own yet. As we get older with more experience, we (as a stereotype of older people) tend to more “set in our own way” perhaps because we consciously or subconsciously believe we have found “the” way.
I think there is a balance between having expertise in a certain area and keeping an open mind for challenges and new ideas; otherwise, we may miss good opportunities and/or come across as dismissive.
