Use a word to describe myself

  There have a lot words in English but which word is the best to describe you? For me, there have more than one but I think 'lazy' is the best word to describe me. Some of the people may say 'active' is the best word to describe me, but is not true. I like to play sports, but sometime I am lazy to run, that's mean I still lazy even I am doing something that will make me look active.
  Sometime my mom will tell me I am a lazy girl too, because sometime when reach home I just doing nothing or just play computer and other stuff, I never do my homework before I play. I don't really like to study, and I don't know that's because I am not using the language that I know really well for my study or other reason. But I think part of the reason is because I am lazy to study about the language I not  really understand.
  There still have more reasons why I use lazy to describe myself, and I think that's the word can be the best one to use for describing me. Now I will try to change myself, I will try not to be lazy this year.
