Speeches / talk about someone in your family who you admire [8]

My english teacher ask me to do this essay about someone I admire, I wonder if you could help me to correct it,if there is any language problem or wrong words, for example. Thank you very much!

We all have someone in our family who we most admire. From my perspective these people are essential for us as we have somebody to mirror ourselves.

In my case, the person I most esteem is certainly my grandfather, whose life story inspires me and even helps me to have a better life.

He was born in Pouso Alegre, a small village in Minas Gerais, son of an idealist journalist who used to fight alongside the small farmers against powerful landowners. He, his mother and brothers used to live happily until the day his dad was murdered. He was just six years old when he started working as a bootblack to help his mother. Life was hard but he never gave up, so after a lot of work and dedication he made his dream and graduated in law in one of the bests colleges in the country.

Everyone have dreams but there are few people in the world strong enough to fight for them. Surely, my grandfather is one of this people. Courage, determination and overrun are the traces of his strong personality that I most prize.

He is also smart and extremely confident. It is always a pleasure to hear his life experiences. I'm looking to follow in his footsteps so that I can be a better person and guarantee a successful future for me.
