1 . We sometimes think that everything was much better and easier in the past. It’s one of the tricks our minds play on us, especially when we arc in low spirits.

Actually, it’s unlikely that things were objectively better in the past. This form of thinking is called rosy retrospection,which is a well-studied cognitive bias. It happens because when we think about the past, we are more likely to focus on positive generalities than annoying details.

If you think back to a holiday with your family five years ago, you’re likely to recall the beautiful views rather than the uncomfortable bed. In other words,the negative details disappear from our memory over time while the positive ones remain.

Rosy retrospection can influence how we make decisions, and it’s one of the reasons why we easily return into problematic relationships. The longer it is since we experienced the negative influence of a relationship, the more likely we are to let the good memories outweigh the bad memories and to perhaps forgive unforgivable behavior. It’s always a good idea to review our nostalgic (怀旧的) feelings with a healthy degree of doubt.

But rosy retrospection does serve an important purpose. It keeps us in a positive state of mind in the present and is important to our psychological wellbeing. In fact, people who tend to remember negative experiences more than positive ones are likely to exhibit psychological disorders. Research generally suggests that our happiest days are still to come. And even if they’re not, it’s still important to believe that they are. Don’t shy away from looking upon the past with a certain degree of nostalgia. But, for the same reason, don’t use the past as an excuse to be unhappy in the present.

3 . For centuries, people have wondered about the strange things that they dream about. Some psychologists say that this nighttime activity of the mind has no special meaning.     1    

Before modern times, many people thought that dreams contained messages from God. It was only in the twentieth century that people started to study dreams in a scientific way.

The Austrian psychologist; Sigmund Freud, was probably the first person to study dreams scientifically.     2     He believed that dreams allow people to express the feeling, thought, and fears that they are afraid to express in real life.

The Swiss psychiatrist (精神病学家) Carl Jung was once a student of Freud’s. Jung, however, had a different idea about dreams. Jung believed that the purpose of a dream was to communicate a message to the dreamer.     3     For example, people who dream about falling may learn that they have too high an opinion of themselves. On the other hand, people who dream about being heroes may learn that they think too little of themselves.

    4     For example, psychologist William Domhoff from the University of California, Santa Cruz, believes that dreams are tightly linked to a person’s daily life, thoughts, and behavior. A criminal, for example, might dream about crime.

Can dreams help us understand ourselves?     5     However, one thing they agree on is this: If you dream that something terrible is going to occur, you shouldn’t panic. The dream may have meaning, but it doesn’t mean that some terrible event will actually take place.

4 . Many of us seem to have lives that follow a certain way. From kindergarten all the way to getting married, every stage of our lives seems to be preset (预置). And although this works well for a lot of people, according to British scholar Jay Shetty, there is no “right” schedule to live our lives by.

A few months ago, a video of Shetty’s speech “Before You Feel Pressure” became popular on the Internet across the world. In the video, he sends an important message that we should think “outside of the way” and have the courage to follow our hearts. As Shetty says in the video, we don’t have to get stressed and put ourselves in the race with our peers (同龄人) or judge our lives based on others’. “Everything in life happens according to our time, our clocks,” he says.

In his inspiring speech, Shetty points out that UK author J. K. Rowing got her famous “Harry Potter” series published at age 32, after being turned down by 12 publishers. Shetty also mentions that Chinese businessman Jack Ma didn’t even start the Alibaba Group until he was 35 years old. So we shouldn’t let anyone rush us.

As physicist Albert Einstein once said, “Not everything that counts can be counted, and not everything that is counted truly counts. The key to staying on our own tracks is to be patient and keep our own interest.” In Australian nurse Bronnie Ware’s best-selling book “The Top Five Regrets of the Dying”, she recorded the dying regrets of her patients, and the top one on the list was: “I wish I had the courage to live a life true to myself, not the one others expected of me.”

Indeed, we are all unique in our personalities and gifts, and there is no perfect fit for all. We should listen to our inner voices and ignore what the world has taught us, and what we have picked up from people around us. “It is important to allow people to go back to being self-aware of their own interests, needs and concerns”, Shetty told the magazine. “It’s disconnecting from what makes sense to what actually moves you and what makes sense internally (内在的).”

7 . In recent years, labels have increasingly been used by the food industry. Whether “non-GMO (转基因)” or “zero trans fat” ,“no added hormones” or “sugar-free”, consumers are demanding more information about what’s in their food.

A report by Nielsen found that 39 percent of consumers would switch from the brands they currently buy to others that provide clearer, more accurate product information. Food manufacturers are using the new labels to meet consumers’ demand, with an eye towards giving their products a leg up over the competition, and their bottom lines a boost as well.

On its face, the new marketing strategy makes sense. But these so-called “absence claims” labels are harmful both to the consumers who purchase the products and the industry that supplies them. For example, Hunt’s put a “non-GMO” label on its tomatoes a few years ago — despite the fact that, at the time, there was no such thing as a GMO tomato on the market. Over the long term, this strategy will have the opposite effect: by creating fear, we run the risk of damaging consumers' trust.

Eventually, it becomes a question in consumers' minds: Should I have ever been eating these foods in the first place? By purchasing and consuming these types of products, have I already done some kind of harm to me?

For food manufacturers, it will damage consumers’ trust, which in turn would lower sales for the whole food industry. And this isn’t just supposition. A recent study by a group of academics at the University of Delaware found that “absence claims” labels can stigmatize (污名化) food produced with conventional processes even when there is no scientific evidence that they cause harm.

In addition to the likely negative long-term impact on sales, it sends a message that innovations in farming and food processing are unwelcome, eventually leading to less efficiency, fewer choices for consumers, and, ultimately, more costly food products. Therefore, it’s clear that food manufacturers must be careful when using “absence claims” as a marketing strategy. If we allow this kind of label fear-mongering to continue, the losers will be all of us.

8 . Making employees feel happy and healthy at work is good for many businesses. But it isn’t always an easy thing. A research suggests that just 33% of the U. S. employees consider themselves fully engaged (投身于) at work, while 16% are actively disengaged, and 51% are just showing up.

But there is an exception. When it comes to employee engagement, it seems that employees in small companies are doing better. According to the same research, the largest U. S. companies have the lowest levels of engagement, while companies with fewer than 25 employees have the highest. And in one recent report, 75 percent of small business workers surveyed said they were “very” or “extremely” satisfied with their role as a small company employee.

Unlike big companies, small companies are often short of resources but the employees can get more surprises there. Small companies offer excellent career opportunities to their employees. The bosses often know their staff very well and understand their personal needs. Employees of small companies are more likely to receive free meals, paid leave, and they can even bring their pets to work.

But of course, there’re many other draws in small businesses. One of the top draws is flexible scheduling (弹性工时). Another is being able to really see the fruits of one’s labor. Besides, noncash award is also a big draw. This could be something small that reflects employees’ interests and lifestyles.

While a parental leave might lead to some financial problems, small companies may do something to improve it. “It may be impossible for a five person team to be reduced to four for six months,” writes Camilla Velasquez, head of HR management platform Just works. “But it could be possible to allow new parents to take on reduced hours in a work from home environment.” This kind of method has been realized in some small companies.
