Behind The Curtain, Angelina Hong Dec 2024

Behind The Curtain, Angelina Hong

HCA Healthcare Journal of Medicine

One of my favorite themes in medicine is the concept of identity. Medicine is layered. It is continually saving lives, expanding in capabilities, and recruiting new students. But how does it shape us, and where does one draw the line between self and profession?

Physicians are classically a symbol of hope and healing. But medicine is challenging physically, emotionally, and spiritually. Add on top of that the daily burdens of our personal lives, and the responsibility can become quite heavy, making it difficult to walk with a smile every day. There is a time to stand behind a “curtain”, for …
