You are an imposter and a fraud, and you’re just pretending you know what you’re doing. There, now that we have that out the way, we can move on; welcome to the club. As someone who has been called an expert many times, I can assure you experts don’t exist. We are all pretending we know what we are doing and we are all making it up as we go. At this point the world is changing so fast that as soon as you think you have a handle on something, the world has already moved on and you are a decade behind. Stop worrying about labels and about being good-enough; just do the work. The ones who call themselves experts are the true imposters.
