How did you decide on your first job?

My first job was a nurse. I've been working in three shifts for almost three years, and I'm nervous because of the night shift and the increasingly difficult patients. When I was young, my thoughts were simple and willful, so I simply resigned to study and save my strength. While studying and practicing, I watched all kinds of people around me work hard in the workplace and found that no one can make big money easily. Behind those glamorous, there are more and more bitter efforts and more intense study. So, I made a decision. I must do this job well and hone myself.
