If you have any of these stories rattling around in the back of your head, it’s time to let them go: I don’t know enough yet. I’m not as smart as others. Everyone is more skilled and better than I am. I am a fraud. I am an impostor. I should know more than I do. If I say I can do something, I’ll fail. It’s best to avoid more responsibility and play small. These stories are toxic sludge. They aren’t true and they don’t serve you or anyone in your company or life.
