Field of Reeds

在不影响健康的情况下晚睡，在不影响心情的情况下早睡, this is a sentence copied from my Douban group. It tells exactly what I have to do now. I kind have a habit of going to bed late, since I have been in Hong Kong, this habit never change. Everytime, my mom told me to go bed early, it is healthy and city people are too careless about their health. I know, and I tried, failed...
The group also summarized a rule of people who have this habit:
以周末的起床时间来给人群分类的，例如：
8：00以前 中老年人
8：00-9：00 小屁孩儿，补课学生，新婚少妇……
9：00-11：00 稍有放纵的小青年
11：00以后 极其潇洒的自由主义者，内心深处住着天山童姥
obviously I belong to the later two groups.
What should I do? yeah! Go to bed as early as I can. Bang now is 12:30 in the evening. Saying is always easier than doing.
