You're right! You shouldn't self-deprecate. That's just, well, self-deprecating. Instead, you should self-appraise. You are good. You are smart. You are capable of a lot of things, including doing your job. You are the best Problem Solver ever. Why worry? Because you care. You care so much about everything. You care about the Queen. You care about your friends. You care about every single living soul on Prospt. You will do your best work. And you'll be ok.
