We live in a culture that sends out very mixed messages about mistakes: We're told we learn by making them, but we work hard to avoid them. So the result is that most of us know that we are going to make mistakes, but deep down, we feel we shouldn't.

    Experiments with schoolchildren who did well on a given test show that those who were praised for being smart and then offered a more challenging or less challenging task afterward usually chose the easier one. On the other hand, children praised for trying hard— rather than being smart—far more often selected the more difficult task.

    If we try hard to avoid mistakes, we aren't open to getting the information we need in order to do better. In a writing study, experiments showed that those who are so scared to make mistakes perform worse in writing tasks than those who aren't as worried about being perfect. They fear receiving any kind of negative feedback, so they don't learn where they went wrong and how to get better.

    We don't just learn more when we're open to mistakes, we learn deeper. Research tells us that if we're only concerned about getting the right answer, we don't always learn the underlying concepts that help us truly understand whatever we're trying to figure out. Mistakes need to be seen not as a failure to learn, but as a guide to what still needs to be learned. As Thomas Edison said, “I am not discouraged, because every abandoned wrong attempt is another step forward."

    Furthermore, we often make mistakes because we try new things—we wander away from accepted paths. Teflon, penicillin—these are examples of great discoveries made by mistake. Take a page from Albert Einstein, who said, "Anyone who has never made a mistake has never tried anything new. "

    When you think of the future,you imagine having some sort of robot friend in your life.Musio,a new robot unveiled recently,is something like that.

    Musio is an artificial intelligence software that runs on Google's Android mobile OS,and is packaged in the form of a round little robot with pointy ears.It doesn't move around,but it has a digital screen for its eyes and heart that are used to express the robot's emotions.It also comes with a remote pointer device,called Sophy,which is used to detect objects that trigger different interactions with Musio.

    The robot was created by AKA,a company specializing in machine learning and natural language processing.It's designed to interact with its users with a voice interface,much like you'd use Siri.But Musio's creators,Wilmington, Delaware-based AKA Study,stress that this is a much different experience than using Siri—Musio can have interactive conversations and remember information about its users,sort of like a little person.Musio can do all sorts of things like controlling home automation and it has a number of integrated sensors.The robot is also programmable and it is able to speak naturally.It is designed to share its emotions via faces on its LCD screen.There are three versions of Musio that vary on hardware.The Simple version has a 1.2GHz dual core processor,1800 mAh battery, 16GB storage and isn't internet connected.It can only recall the last five conversations it has.

    Beyond running on the open source Android platform,Musio is also Arduino compatible.The Arduino platform is an open source electronics platform built to be easy to program.Its purpose is to take different inputs through a suite of sensors and then relay commands to lights,motors,or actuators as a result.Musio is also compatible with the Zigbee wireless standard used by a range of smart home devices,so it's possible that developers could intertwine the robot with other appliances and turn it into a sort of voice-activated smart home hub with a personality.

    And there are several educational accessories that come with Musio,such as flash cards and a fold-out accordion board book.Using Sophy,the pointer,Musio can interact with these objects thanks to a Bluetooth low-energy connection and a special code implanted in the printed materials.

    China's Singles Day, which falls on Nov. 11 every year, has far surpassed its U. S. counterparts of Black Friday and Cyber Monday—combined Last year, Americans spent a record $ 12.8 billion online between Thanksgiving Day and Cyber Monday. It's impressive until you compare it to the $ 17.6 billion in sales made by Chinese consumers in a single 24-hour period during 2016's Singles Day.

    Singles Day is known as “Bare Sticks Day” or “Bare Branches Day” in Chinese-because the date “11/11” looks like bare branches and “one” is the loneliest number. Singles Day began in the early 1990s in the dorm rooms of Nanjing University when a group of single friends were sorry about the lack of significant others and decided to mark the day by organizing activities as a group of singles and reducing their loneliness by buying themselves a gift.

    Then in 2009, sensing a break between the sales period of China's National Day on Oct. 1 and Chinese New Year in late January or early February, Alibaba's Jack Ma saw an opening: sell to comfort lonely hearts.

    The first year did only $7.5 million in sales, but just 8 years later, shoppers spent $ 25.3 billion, or 168.2 billion yuan, this year—a 40 percent jump from last year's $ 17.6 billion. For comparison, Black Friday and Cyber Monday in the U. S. only netted $ 6.79 billion in 2016. Amazon doesn't release sales figures for July's Prime Day, but it's pretty safe to believe the not-quite-national-holiday doesn't come close to $ 25 billion.

    “More than $ 25 billion in one day is not just a sales figure,” Alibaba Group CEO Daniel Zhang said in a statement. “It represents the desire for quality consumption of the Chinese consumer, and it reflects how merchants and consumers alike have now fully accepted the combination of online and offline sales.”

    You can't always predict a heavy rain or remember your umbrella. But designer Mikhail Belvacv doesn't think that forgetting to check the weather forecast before heading out should result in you getting wet.

    That's why he created Lampbrella, a lamp post with its own rain sensing umbrella.

    The designer says he came up with the idea after watching people get wet on streets in Russia. "Once, I was driving on a central Saint Petersburg street and saw the street lamps lighting up people trying to hide from the rain. I thought it would be appropriate to have a canopy(伞蓬) built into a street lamp," he said.

    The Lampbrella is a standard-looking street lamp fitted with an umbrella canopy. It has a built-in electric motor which can open or close the umbrella on demand. Sensors (传感器)then ensure that the umbrella offers pedestrians shelter whenever it starts raining.

    In addition to the rain sensor, there's also a 360 motion sensor on the fiberglass street lamp which detects whether anyone's using the Lampbrella. After three minutes of not being used the canopy is closed.

    According to the designer, the Lampbrella would move at a relatively low speed, so as not to cause harm to the pedestrians. Besides, it would be grounded to protect from possible lighting strike. Each Lampbrella would offer enough shelter for several people. Being installed at 2 meters off the ground it would only be a danger for the tallest of pedestrians.

    While there are no plans to take Lampbrella into production, Belyaev says he recently introduced his creation to one Moscow Department and insists this creation should be installed on the street where a lot of people walk but there are no canopies to provide shelter.

    I stopped to watch my little girl busy playing in her room. In one hand was a plastic phone; in the other a toy. I listened as she was speaking to her make-believe little friend and I'll never forget the words she said, even though it was imagined.

    She said, "Suzie's in the corner because she's not been very good. She didn't listen to a word I said or do the things she should." In the corner I saw her baby doll well dressed. It was obvious that she'd been put there to sit alone and think.

    My daughter continued her "conversation", as I sat down on the floor. She said, "I'm all fed up and I just don't know what to do with her any more. She cries whenever I have to work and wants to play games too. She tries to help me with the dishes, but her arms just cannot reach... And she doesn't know how to fold towels. I don't have the time to teach. I have a lot of work to do and a big house to keep clean. I don't have the time to sit and play - don't you know what I mean?"

    And that day I thought a lot about making some changes in my life, after listening to her innocent words cut me like a knife. I hadn't been paying enough attention to what I hold most dear. I'd been caught up in responsibilities that increased throughout the years.

    But now my attitude has changed because in my heart I realize that I've seen the world in a different light through my little darling's eyes. So let the cobwebs (蜘蛛网) cut the corners and the dust bunny rabbit rule the floor. I'm not going to worry about keeping up with them any more.

    I'm going to fill the house with memories of a child and her mother, for we have only one childhood and we will never get another.

A few years ago, I returned from a family vacation in Mexico, where I'd bought myself a beautiful blue candle. I was so excited to light it. But when I got home and unpacked it, I thought, "Today is not the day. I'm going to save it for the right occasion." So I put it in my closet and forgot about it.

Two years passed, I remembered my candle and I thought, "Today is the day. I'm going to light it." So I went to the closet and opened up the box—and my beautiful blue candle had turned into wax. Now what struck me is my candle did exactly what it's designed to do—melt—but it did it without me.

That candle which melted triggered (触发) something in me. It old the story to my friend Gillian. The next time I was over at her house, she took me on a tour and she showed me that all of her candles had been lit. She told me, "I had waited a year to light those candles. You told me the story, and I lit them all the next day. "

I believe, however, that those small actions send a big message and show you're no longer letting life slip— or melt—by.

Here's my advice for you: Whatever object you answered "yes" to earlier, please use it with in the next week. Pull out your china for a random Tuesday night, open the Scotch, and cut the tags off a jacket. And don't let your candle melt in the closet.
