My 30 day challenge

Do you know about the 30-day challenge? It is a challenge to achieve in 30 days. I am going to introduce my 3 goals to achieve in 30-days.
My first goal is to earn many green cards.To make this goal come true, I have to listen carefully in class of course, and I should be active and get along with friends well. I want to get green cards because green cards give us benefits. We can be smart and good student. Second, I want to lose 2 kg. To achieve my goal, I shouldn't eat fast food because it makes us fat and unhealthy. Also, I will exercise everyday. If I do these things, I will lose weight and be healthy. Third, I will make many friends. Since I'm in camp, I should make new friends. I've already made 18 friends. But, I want to make more friends. To make more friends, I should be kind to my friends and I should be active and have manners. I want to achieve these 3 goals. I think it will be good and can be helpful if I improve my English skills in future.
