Undergraduate / US Prep school admission essay -- my future dream of being a diplomat [7]

I imagine myself attending the commencement at WA, being proud of having acquired the important skills for my future dream of being a diplomat. WA enjoys a unique diversity, which is not to be found anywhere else. Each student from his own homeland brings in a new taste of culture and mutual understanding. This advantage gives me the chance to learn firsthand how people from every walk of life think and live. Having a brief but exact knowledge about cultures and traditions enables me, a future global citizen and a diplomat, to make a quick adjustment while working overseas. WA also offers me an opportunity to try many things that I wo'nt be able to do in Vietnam. I can learn a totally new foreign language to explore a new culture. I can also join a debate club to strengthen my speaking and critical thinking abilities. At the moment, I am holding the position of the School Student Discipline Committee, which gives me a sense of confidence and leadership.the experienced and responsible teaching staff at Wasatch Academy can provide me with the knowledge I need in both life and future career. i would love to learn from the best teachers in the best classes that WA has to offer. there's a strong belief in me that all of my hidden talents or abilities can be explored and developed during the years at WA. Deep in my heart, I understand that after three years there, I would leave this place with more than what I walked in with. And I believe WA is the perfect environment where my dreams will take flight, and many other treasures will be found.

please correct it. this means a lot to me. it's my life. thank you for your time
