Impostor Syndrome Yeah, maybe I have this syndrome too. The impostor syndrome is when a capable person thinks that he is not capable. Or when someone don't have confidence with what he does. It's more common than you think. Sometimes people say to me: You're an incredible professional, but I think, no I am not. I think this problem is very common in areas of work. I am not alone. Many people fell fear when they have to do something, when they have to speak publicly, for example. There's one way. Don't worry. Just try it.
