Our schooldays are the best and happiest days in our life. We should learn not to waste this wonderful time.
Be positive (积极的). Don't say things are difficult or boring. We should be interested in the school life and school subjects, such as Chinese, maths and so on. We should join in lots of activities. We will enjoy ourselves very much. If we want to have a rest from schoolwork, we can go to some public places to do volunteer work (义工).
Keep healthy. We need to have a good breakfast so that we won't be hungry in class. If we go to bed late, play the phone until (直到) midnight and don't get enough sleep, we will feel sleepy in class. In order to keep our body healthy, we should also do some sports.
Study hard right now. Some students always say that they will study hard tomorrow. It is important to study today and the following every day. Everyone wants to be the first one to get to the top of mountain. In fact, if we fall behind, it will be very difficult for us to catch up (赶上).
Don't be too disappointed (失望) if things sometimes go badly wrong. We should always believe that we are the best.
