How should I start writing my personal statement?

This statement is for college admissions.

First, perhaps a little about myself. I was born and raised in taiwan until 6 yearsold, where I moved to the us. My mom (taiwanese) is handicapped with post-polio. My dad (american), stays at home, and doesn’t work. My mom despite her handicap, and lack of english skills, went to college when we moved to the us and got her BS, and now is our main source of income. I go to a pretty good high school, take rigorous courses. i am involved with robotics club, play the violin in school.

I cant think of a good topic. i can think about how my mom being handicapped has made me who I am, but I have no idea how to start…!
