What is a skill residency didn't prepare you well on for your career and one that did?

When trying to rank my programs, I realized each program was unique, either with more psychotherapy or neuro based, different variety of populations, different experts, ect. So what skillset from residency did you wish you learned from residency, and what skillset did the residency program teach you that was valuable to your practice/job/outside of work?
