     When I was a child, my mom was pushed me to study hard, hoping I could get a chance to go to

college. I experience pressure for the first time. I did that my mom expected because I didn't want to

let her off. I was born to a poor peasant family, but I really knew life was not easy. All the things my

mother did was the result of her hope that I could lead better life in the future. As the saying go, "No

pains, no gains." I was finally able to meet my mother expectations and have a chance to go to college.

Thanks to my mother's push and the pressure, I made it. Now, I no longer think pressure is a good thing.
