Imposter syndrome

If you're reading this, you've probably heard of imposter syndrome before - that feeling that, deep down, you don't really deserve praise or recognition for your supposed achievements, because you feel like you're not as good at this stuff as your colleagues/competitors, who must really know what they're doing.  As one of my grad school roommates said as a bunch of us were struggling with homework:  "Here we are, students in one of the most prestigious graduate programs in the country.  I sure hope someone knows what they're doing."  

This feeling can be particularly prevalent in fields where there is great currency in the perception of intellectual standing (like academia, especially in science).  My impression is that a large majority of physicists at all levels (faculty, postdocs, grad students, undergrads) experience this to greater or lesser degrees and frequencies.  We're trained to think critically, and driven people tend to overthink things. If you're fighting with something (some homework set, or some experiment, or getting some paper out, or writing a proposal), and your perception is that others around you are succeeding while you feel like you're struggling, it's not surprising that self-doubt can creep in.  

I'm not posting because I've had a great insight into mitigating these feelings (though here are some tips).  I'm posting just to say to readers who feel like that sometimes: you're not alone.
