What is Imposter Syndrome?

When I first started talking about imposter syndrome in podcasts, on social media, or on the blog, I got a lot of people with the same response.

“Wait, what is imposter syndrome?!”

I had no idea that it wasn’t a topic widely known. I assumed that the people I was coming into contact with knew what I was talking about. So rather than assume others know what it is, I decided to answer the question myself.
