Purpose and meaning of life

Who am I? This is very good question that we thought we can answer by our self but this is hard to find about our self that who we are? I would say overall i m good person, very friendly, good student, always positive, thinking good always, try to help someone in bad situation or in trouble. I am senior in high school, and I want to be engineer. I am new in USA because I just came here 2 years ago from India. I finish my 10th grade in India, and I got an award in my native language; I got first number in whole state. I had very hard time learning English and try to understand American people like how they talk to other people. However, last year I got an award in school about best effort in English. I had encourage by lot of people in school, and they taught me lot of good things.I came to USA for my bright future and want to get good job to get more money. Therefore, I live with my parents and my uncle-aunt in USA.
Biggest influence in my life is from my parents that i have to work hard in USA because they live here for me. Also, they have lot of hopes for me that i will work hard, and get a good job after college. They always thought me good things what should i do? That makes me more influence in my life that i have to work hard no matter what. In addition, my school teachers influence me lot by like never ever give up. Always, try something to do something new. they have lot of high expectation about me.
My goals are getting in good college, get good job, try to help my parents, and become a good engineer. My goals for future are getting new home, business, and some money spending in charity. Goals is not like what you think that what we are going to do, but we have to work hard to achieve that goals. Purpose of my life is that try to be a good to everyone, help people in any situation, learn something new about different people, culture and world. Also, live a good life that does not mean you live a good life but try to help someone, be friendly, honest, and respectful to other people and that people talk about you after you died. That means you had a good life and you purpose are becoming successful. Another purpose of my life is praying to God, obey my parents, listen all people when they give a advice. So, overall i would say do something that makes your life smooth, easy, and successful.
Thank You.
