I found this post this afternoon that might be of some interest to fellow graduate students. In this gig we’re surrounded by smart people and it’s easy to start believing you’re just not up to the same level as your classmates, i.e. you feel like an impostor that will eventually be discovered for the dolt that you are.
The post is about how most graduate students feel this way, why, and why they are nearly always wrong. Worth reading, especially if you’re doubting yourself.
