1 . Life is full of surprises. You never know what’s going to happen from one day to the next.    1    It can also be anxious. When something happens that you didn’t expect, it throws your whole world off balance. This can lead to negative feelings.

One way to fight against these negative feelings is through optimism,    2    Optimism is a mental attitude that sees new things as opportunities, transitions as improvements, and challenges as learning experiences.

    3    This gives you more power over your life and what happens to it, which can help prevent anxiety and depression. This can also help improve physical health in turn over time.

When something bad happens, optimists are less likely than pessimists to blame themselves or others for what happened. They don’t consider these negative emotions. They are able to see things from a positive perspective, even when something doesn’t go as planned.    4    

So it’s important to face bad things bravely and keep a positive mind. Of course, it’s important to remember that optimism can’t put a stop to all bad things.    5    But if you can manage to focus more on the good than the bad, you’ll be less anxious and be well on your way to a happier and healthier life.

2 . Do you have one of those days when everything seems to annoy you? Even if you do nothing about it, your bad moods will probably go away after some time.     1    

Give yourself a positive talk.     2     Bad moods are often started by too many negative thoughts. Write them all down on paper and then give optimistic answers. Then try your best to think and behave positively.

    3     Exercise is the most popular bad-mood buster (遏制者). A person who is in a bad mood has low energy and high tension. Taking a fast ten-minute walk or doing some quick exercises can do wonders towards changing that bad mood. However, you should pay attention to the length of time.

Avoid things that won't improve your moods. TV may not help much, because you need to increase your energy level and stimulate your mind. And before you reach for a piece of cake and coffee, think about how moods and food are linked.     4     Research shows that carbohydrates (碳水化合物) produce a calming effect on people who have a desire for   them.

Another simple way to be against unhappiness is to make a to-do list. One reason for being in a bad mood is feeling you have no options. By taking control over certain areas, your realize you are not helpless.     5
