T change bad habits is never easy, even with many attempts. There is a famus saying based n the philsphy f Aristtle: “We are what we repeatedly d.” In many ways, ur lifestyle is the sum f chices we have made. We make a chice t d smething, and then we repeat it ver and ver again. Sn that chice becmes autmatic and frms a habit that is much harder t change. The gd news is that we can change, if we understand hw habits wrk.
改变不良习惯从来都不是一件容易的事情，即使你三番五次地尝试。有句基于亚里士多德哲学的名言："我们反复做的事情造就了我们。"从很多方面看，我们的生活方式是我们所作出的选择的总和。我们选择做某件事，接着我们反反复复地做这件事。不久之后，这项选择就变得自然而然，成为一种更加难以改变的习惯。好消息是，如果我们了解习惯是怎么运作的，我们就可以作出改变。

Accrding t mdern psychlgy, we must first learn abut the “habit cycle”, which wrks like this: Firstly, there is a “cue”, an actin, event, r situatin that acts as a signal t d smething. Secndly, there is a “rutine”, the regular actin yu take in respnse t the cue. Thirdly, there is the “reward”, the gd thing r feeling we get frm the rutine.Fr example, when we feel unhappy (cue), we eat lts f unhealthy snacks (rutine), which makes us feel happy (reward). The reward makes us much mre likely t cntinue the cycle, and the bad habit f relying n unhealthy snacks is frmed.
根据现代心理学，我们必须首先了解"习惯循环"，其工作原理如下：第一是"触发因素"，即一个行动、事件或状况，充当要做某事的讯号。第二是"惯常行为"，即你响应触发因素而采取的常规行动。第三是"回报"，即我们从惯常行为中获得的美好事物或感受。
T facilitate a psitive change in ur bad habits, we must first examine ur bad habit cycles and then try t adapt them. We can d this by cmbining the infrmatin frm ur habit cycles with ur wn psitive ideas. Fr example, we culd try t replace a negative rutine with smething mre psitive. S, when we feel unhappy again (cue), rather than eat snacks, we culd listen t sme f ur favurite music instead (rutine), which will make us feel relaxed (reward). Aside frm changing bad habits, we can als use the habit cycle t create gd habits. Fr example, when we cme t an escalatr (cue), ur nrmal rutine is t ride it, but we culd change this rutine int smething mre psitive by taking the stairs instead.

Many f us try t change bad habits quickly, and if we are nt successful straight away, we ften becme pessimistic and give up. In fact, the mst successful way t change is nt suddenly, but ver a perid f time. As the Chinese philspher La Zi wrte, “A jurney f a thusand miles begins with a single step.” One step seems small, but it is essential. T reach the gal f change, a persn must shw sme discipline and repeatedly take many small steps. After all, it is nt easy t break bad habits.
be pessimistic abut
汉译英：Mr. Cai不是一个足球运动员，而是一个明星。
