"The word 'physician' originally meant 'educator' and this designation still holds true today as many physicians are involved in teaching residents, students, and patients. My undergraduate career has instilled a deep passion within me for education, and I strongly desire to become a physician teaching the next generation, because they are our future. I believe that if they are taught well, they will lead the way. Everyone needs a hero and life can be a challenge. People need someone to look up to. I never found anyone who fulfilled my needs, and so I learned to depend on me. But in order for me to be the one to inspire my students and patients, I must start believing through my heart and my soul in changing the world. And so I hope to become a physician with a gift to dream and to make dreams real. Yours and mine."
That should hit the 1000 character limit I think.
