I've wanted to be a doctor since I was 14 years old. I've always had an affinity for science and math, and I was a precocious child in regard to social skills. But it wasn't until an annual wellness checkup that I wanted to be a doctor. The doctor, my family's GP of many years, asked me how school was going, which led to me asking him what medical school was like. We chatted a little bit more, and then the conversation subsided. A few minutes later, after he was finished listening to my heart, he frankly said, "I think you'd be a great doctor." As simple as that statement was, it really resonated with me. In the following weeks, I researched medicine and the road to becoming a physician. I became more fascinated by the profession after every article I read, video I watched, and interview I listened to. After a few months, I started volunteering at a local hospital, and about a year later I finally got to shadow my family doctor--the same one who inspired me to go into medicine; he was absolutely delighted to see my interest in and enthusiasm for a career as a physician.
TL;DR -- I was 14. 🙂
