I am interested at swimming very much. At first, I went swimming just to keep health. Now my dream was to swim for my country in the Olympics. Though practicing in the pool is very bored, but I still work very hard in order to realize my dream. Because my hard work, I have already come first in much important competitions. In the competitions, I’ve made lot of friends and we’re very close. It’s much easier to have friends which are swimmers because they also have to get up early to practice like you and they understand this kind of life.
