Прошу проверьте на грамматику и стилистику сочинения по Английскому языку...

Задание: Короткое сочинение (для отбора студентов, которые дали заявку на прохождение практики за границей.)
Тема: Почему именно я должен поехать на практику.
Прошу проверьте норм написано или нет (словосочетания, предлоги, обороты, и по смыслу может что переставить заменить), а то давно я официального ничего не писал.
Заранее спасибо всем, кто уделил внимание))

Why precisely I should be at the practice abroad?
Let me introduce myself. I am Name Surname. I was born in 1991 in Krasnodar city. So it happened that both of my parents are medics. My father over 20 years is a surgeon and now he works in a surgical department of the military Hospital. My mother is a dentist in a private clinic. I think that is a good tradition in our family and my calling is to become a physician.
I was interested in biology, medicine and chemistry since high school. And after graduation, I had no choice but to go to Medical University. Here I fell on myself that being a physician is hard work requiring a full commitment.
I believe that the practice abroad will help me learn more aspects of this interesting and important profession. Also this is a unique experience to communicate with new people and to know something new directly from the specialists. It would be nice to make new friends and get to know the culture of the country.
I try to do my all best to become a good physician and I think that this practice will help me on my way at medicine.
