Any critique and advice is welcomed. Please tell me if this is good or not. Thank you very much for your time!
Prompt: Expand on one of your extracurricular activities or work experiences.

Trying out for drill team was one of the best decisions I made in High School. It shaped me into a more confident, responsible and committed person. Performing in front of an audience allowed me to Iose the fear of being in the spotlight and learn how to smile no matter what happened. Drill team taught me that in order to succeed at things you like, you are responsible for the work. As a member of this organization, I found that I was responsible for the effort put in practice, being well prepared all the time and contributing positively to our team. I found myself spending a great amount of time with my team, which helped me experience the feeling of being committed to something and dedicating myself to it. These are things that I will carry with me my entire life and that are essential in order to enjoy and be great at anything you chose to do. I love Drill Team and thanks to being a part of it I was able to live unforgettable experiences with my teammates.

I think one way to make this essay better would be to end the essay with how being a part of the drill team and shaped or inspired you in some way. This could potentially make it a much stronger essay.

I agree with rxa0789, I would like to see more details about your experience, maybe even a short anecdote? To me this essay seems weak because it's really vague and kind of repetitive. Maybe just focus on one aspect and expand on it. Also, since I'm not from the US I didn't really get what drill team actually was... If you could bring that out by describing what exactly you did I think that would be good for your essay as well. :)
