Correção de texto "If you could change something..."

Olá pessoal, o tema da redação é o seguinte "If you could change something really in your life, what would you do? why?"

Nowadays I work with Information Technology, but if i could something really in my life certainly one thing to do is change my career and if I can I become a successful soccer player, because it’s my big dream since when I was I child, and I always like to do sports, but soccer is my favorite sport to practice.
First off all In my family I always saw my father and my brother practice sports. My father ever did jog at Freguesia Park to give a healthy life, and my brother played soccer at the Bangu Athletic Club , and Olaria Athletic Club. Because my family costums I always like to practice sports to get I healthy life , and because since when I was I child I like.
Another thing about it, in my childhood I always play soccer with my friends where I grew up, but the principal reason wich I have my dream to become a soccer player is because I always saw my brother play soccer at the soccer teams in the championships. When my brother played at Bangu and Olaria I went all the games against others teams, and when saw my brother in the soccer field I wish to do the same thing.
Work in IT isn’t bad, you can work in a good company and get an excellent salary, my sister for example work with IT at the Brazilian Navy, and she like to much. Anyway I don’t hope continue work with IT , if I don’t get become a soccer player i’ll study Physical Education to work with sports.
To finish I hope change my life coming soon because I don’t like to work in Information Technology, I hope become a successful soccer player but if I don’t get this I want to be a renamed fitness coach.
