"Whether you are an astronomer or a life scientist, geophysicist, or a pilot, you've got to be there because you believe you are good in your field, and you can contribute, not because you are going to get a lot of fame or whatever when you get back"

Thinking in your skills and knowledge fuels passion and perseverance, allowing you to confront challenges and push boundaries.

This element of professional life underscores a sense of function that transcends personal accomplishment and concentrates on the wider effect of one's work.

Shepard suggests that while public acclaim may be a byproduct of excellence, it shouldn't be the driving force. A concentrate on external recognition can lead to burnout or disillusionment, as it places one's sense of worth in the hands of others rather than within oneself.
