When we feel unhappy again(cue), rather than eat snacks, we could listen to some of our favourite music instead(routine), which will make us feel relaxed. Aside changing bad habits, we can also use the habit cycle to create good habits. For example, when we come to an escalator, our normal routine is to ride it, but we could change this routine into something more positive by (take) the stairs instead.
Many of us try to change bad habits quickly, and we are not successful straight away, we often become pessimistic and give up. In fact, the (successful) way to change is not suddenly, but over a period of time. As the Chinese philosopher Lao Zi wrote, "A journey of a thousand miles begins with single step." One step (seem) small, but it is essential. To reach the goal of change, a person must show some discipline and (repeat) take many small steps. After all, it is not easy to break bad habits.
For young people, there is plenty of time to change bad habits. However, there (be) no "magic pill" or delete button that will help you; you have to think about your bad habits and determine to make some (change). You have the power ( build) a happy and healthy life full of good habits!
