There's a term known as "impostor syndrome," the feeling a person gets when they doubt their own accomplishments and irrationally fear being outed as a fraud. As a somewhat-known figure in certain small Internet circles who was broke and living with my parents all of five minutes ago, I've fought a few bouts with this phenomenon. The worst cases occur with a few of my better project cars—more specifically, at the point in my build that my car, after all the money and effort poured into it, bears no resemblance to my usual rough-around-the-edges projects, and I'm just waiting for someone in authority to tell me that I don't have any right to own it. Actually, I kind of hope that last part happens because that would mean I get to finally stop spending money like I'm speedrunning bankruptcy.
