This is a follow up question to How do I know if I'm good enough to be a math professor? where the poster is asking about whether graduate school is a good choice.
I am due to finish my PhD soon and have the same question - should I pursue a postdoc and aim for an academic career. How do I know if I am "good enough"? Presumably the same question would apply after the first postdoc.
A postdoc/PhD student has a few extra indicators that an undergraduate student doesn't have, namely some journal publications, citations & research experience.
What should they be looking for to honestly self-evaluate their chances? Is publication count/journal quality/citations a good metric? In which case how should they go about comparing with their peers within their sub-field? Or are there other metrics that are more important/indicative?
In my specific case I am in engineering (fluid mechanics) if this matters.
