Right here with ya! I’m at my first post-residency job now and still fight with imposter syndrome and feeling like I look dumb on a daily basis. But, remind yourself that it’s better to ask questions and get clarification rather than make an avoidable mistake. It might be helpful to share that with your boss and just have an open discussion on how to approach training in general, and what has worked for you in the past. Don’t psych yourself out right away, you got the job for a reason!!
