Do I have a role model?

I was reading "Mindset" by Carol Dweck when I found I don't have any role model for my career.

When I finished medical school, I found no interest to be a real doctor, and neither when I finished the USMLE in US 17 years later. Still I had no role model of physician even I thought I might be a good doctor. As a neurobiologist for 20 years, I have been very dedicated to this career and were quite productive by publication, yet I don't have a strong role model in my mind.

Fetching from my memory, Richard Dawkins and Stephen Gould could be the role model for science writing; Erich Kendal could be the role model for neurobiologist; Seymour Benzer could be the role model for geneticist; and Thomas Edison could be the role model for inventor...
