Every morning, when I wake up, the first thing that comes into my mind is not what I should eat for breakfast, it's my phone. I usually rush into the bathroom with my phone and sit on the toilet for a long time until other family members ask me to get out. These attractive videos from Wechat the must-have apps on my phone are more important than a tasty breakfast.Later, I eat my breakfast while watching videos on my phone. I often forget what I have eaten ,but I remember what I just watched. When I get into elevators, I habitually take out my phone and open the apps I have opened millions of times. I often forget to press the number of my floor. When I go to an appointment with my doctor, I open the app and do something fun, never mind what the doctor says. I give likes to the videos I like, I skip the videos one after one. One year quickly passed. On New Year’s Eve, I warned myself to keep far away from the phone next year, and set a goal to achieve, but the New Year‘s resolution just kept for a few hours. The next day, the next year, I woke up with the magic of my phone. I mechanically took my phone into the bathroom......Maybe I need to hear the song "Free Loop" at that moment. So, what the must-have apps are? Must I have them?
