Why Choose a Career in STEM I chose a career in the field of STEM not because it is popular, trending, or have an increasing demand for their careers but because I felt I could help the most people through STEM. Although the money that these STEM jobs pay is good I wouldn't want to be paid for something if it wasn't helping someone improve in their life, and I believe careers in STEM do this the most. I believe my career choice, Orthopedic Surgeon, can help many people physically, emotionally, and mentally. I also chose this career because I like a challenge. Going to the hospital or clinic to see a doctor can be nerve racking and making the patient comfortable with you can prove challenging along with having their health in your hands, but the end result being improved health of the patient makes that challenge very worth it.
