A fear that teachers or colleagues will realise you have no real grasp on the work. A snake of insecurity that means you can't comprehend how you deserve to be part of a friendship circle. A shiver of apprehension every time you have to present something because of a belief that your ideas or results can’t possibly be enough. Or – as in my case – a cold, constant voice in the back of your head telling you that you are not really a writer, that you’ve been fooling everyone and one day they’ll turn on you because of it. Oh yes, it’s time to talk Impostor Syndrome.
