Impostor Sindram, Only if I'm Doing Good Work

The author talks about the notion of impostor sindram. The feeling that we have of being a fraud when we're about to lead or do something important. And i think i read this correctly, you still feel that way sometimes. Why? Because good work for me is work that i'm not sure is going to work. I'm asserting something about the future, and 'm not sure. So who am i to show up and say, yes, i think x or this might work?"
