Undergraduate / Essay on challenges and rewards of living in a boarding school [5]

I am applying for this school and I have to write a 150-word essay "Explaining what you expect to be the challenges and rewards of living in a boarding school". I have rewritten it 3 times already but I still feel it's too broad and not specific enough. Please give me comments on my essay and help check with the content. Should I write it in another way??. Besides, my essay is 245 words now. Could you please cut it out for me also?

Thanks a zillion times :D :D :D

" Boarding school is no difference from a society where I experience every situation, discover who I am, make friends for life, and become a successful young adult.

The best part of going to a boarding school is the people I would meet there. Living among people from all over the world, I would learn about distinguish cultures and styles of living so that I will respect others and their nations more. Being a boarder, I would gradually learn to live independently, respectfully and responsibly as well as become more adaptive. Besides, boarding schools allow me to discover who I am and explore my hidden talents by promising a better academic with strong and broad foundation in every subject as well as shaping the students' characteristics and social skills with number of extra-curricular activities. Along with all the rewards the school offers me , I also expect some challenges namely catching up with a new education systems and adjusting lives with people I have never met before. However, the load of curriculum and extracurricular activities would soon blow those challenges off and I would definitely gain a lot of skills once I overcome the hardship

No matter it's college life or after that, I truly believe that rewards and difficulties I have experienced at a boarding school will help me to define myself and turn me into a well-rounded young adult who is not only knowledgeable but also very dynamic and responsible in everything she does"
