作文应该会给你一些要求的，你可以按照要求去写啊，不过还是给你一篇，希望可以帮助到你英语作文高中生活。
During my high school period, I was always looking forward to experiencing a new life in the university. I felt tight and tense towards my high school life since there was lots of homework for each subject everyday. The schedule was full forever, and it's impossible to take a break especially in my 12th grade. Now finally I can step out from my “old life”, and start enjoying my new adventure in the university. However, life in the university is not quite the same as I imagined. It is true that nowadays I am able to get a flexible schedule, but at the same time, it requires you to be self-disciplined. Most people say it is easy to be self-disciplined, however, I don’t really agree with them. In high school, the high school teachers will arrange your schedule; therefore, you did not have to worry about it. However, now you have to arrange it by yourself, and this is not a piece of cake! If your personality is kind of sloppy, you will easily mess up your life in the university, which may lead you to be a loser at the end of your university life. I suggest that we should think about our “new life” seriously. There is no free lunch in this world!
