When I was about 12, I had an enemy, a girl who liked to point out my shortcomings(缺点). Week by week her list grew: I was very thin, I wasn't a good student, I talked too much, I was too proud, and so on. I tried to hear all this as long as I could. At last, I became very angry. I ran to my father with tears in my eyes.

    He listened to me quietly, and then he asked, “Are the things she says true or not? Janet, didn't you ever wonder what you're really like? Well, you now have that girl's opinion. Go and make a list of everything she said and mark the points that are true. Pay no attention to the other things she said.”

    I did as he told me. To my great surprise, I discovered that about half the things were true. Some of them I couldn't change (like being very thin), but a good number I could—and suddenly I wanted to change. For the first time I got a fairly clear picture of myself.

    I brought the list back to Daddy. He refused to take it. “That's just for you,” he said. “You know better than anyone else the truth about yourself. But you have to learn to listen, not just close your ears in anger and feel hurt. When something said about you is true, you'll find it will be of help to you. Our world is full of people who think they know your duty. Don't shut your ears. Listen to them all, but hear the truth and do what you know is the right thing to do.”

    Daddy's advice has returned to me at many important moments. In my life, I've never had a better piece of advice.

    Christmas was near a season that we took seriously in our house. But a week or so before the 25th, my father would give each of his children $ 20. This was the 1970s, and $ 20 was quite a bit of money.

    But I saw it differently. My father trusted me to have the smart to spend money wisely. Even better, he gave me the means to get it. On a very basic level, my father was giving me a shopping spree (狂欢) every year.. But he was also giving me charge over my own fun, trusting my ability to manage money and making me feel like a grown-up. He didn't buy me Sherlock Holmes, but he gave me the means to walk into the bookstore and choose it for myself, so it felt like a gift from him.

    My mother had a gift for giving me what I needed, usually right at the moment I needed it most. This was when I was 25, I failed at being an adult on my very first try. I had quitted my previous job but had no new one. But when my mother paid me a visit, I put on a good show, telling her I had started my own company.

    My mother knew that I was trying hard and failing at that time. It wasn't until after she left that I noticed at the foot of my bed an envelope thick with cash. She knew how desperately I needed it. She knew that had she just shown up with groceries, or offered to pay my rent, she would have made me feel much worse. The cold, hard cash meant she was helping me. And, funnily enough, the distance with which she gave the gift felt like she was giving me space to fix my life and preserve my dignity. My mother and father both did the same thing. One was giving me the means to take my own decisions, and the other was giving me a second chance when those decisions had cost me dearly.

    An Oceans Vacuum

    There's a collection of plastic trash in the middle of the Pacific Ocean. It's bigger than Texas-and growing. The way to clean it up now is to catch it with nets. That is both costly and slow. Instead, the Ocean Cleanup Project proposes 62-mile-long floating barriers that would use natural currents to trap trash. If next year's trials succeed, a full cleanup operation would aim to start in 2020. It could reduce the trash by 42% over 10 years.

    Easy-On Shoes

    In 2012, Mathew Walzer, a high school student with a disability, sent a note to Nike. “My dream is to go to college,” he wrote, “without having to worry about someone coming to tie my shoes every day.” Nike assigned a design team to the challenge. This year, they came out with their solution: the FlyEase. The basketball shoe can be fastened with one hand. A pair of Nike FlyEase shoes sells for $130.

    An Airport for Drones(无人机)

    As Amazon, Google, and others get ready for drone delivery service, there is one big question: what kinds of home bases will their drones have? Rwanda, in Africa, may have the answer. There, workers will soon start work on three “drone ports”. The goal is to make it easier to transport food, medical supplies, electronics, and other goods through the hilly countryside. Construction is set to be completed in 2020.

    These days, North Kickapoo Street in Shawnee, Oklahoma, is a four-lane road leading out to the highway, and lined with all kinds of places to eat and shop. But in the mid-1950s, it was just a gravel(砂砾) country road, the perfect place for our daddies to teach us how to drive.

We didn't have driver's education at Shawnee High School. We were on our own. Mom took me to pick up an instruction handbook. I was the oldest of my friends, so we were excited at the prospect of a whole new world opening up. We'd have freedom to get around. Best of all, we could go to the Starlite Drive—In theater on 50-cents-a-carload night. We'd have it made.

    Mom let me back our 1949 Ford out of the garage a few times to get used to the clutch (离合器) and gearshift (变速排挡杆). I got familiar with the motion but was hardly ready for my road test.

    Finally, the day came for Daddy to give me a real lesson. He drove out to the end of the paved section of Kickapoo Street and across to where the gravel started. My daddy had come from a family of 10, and they had been farmers in a poor area in Oklahoma. There was only one way to do things, and that was the right way.

Praises were rare, so when he expressed his approval it was special. I didn't want to experience his glare if I ground the clutch or the car shook as I tried to get it going.

    I took a deep breath, slowly let out the clutch, pushed the stick into second gear, eased down the road, and then carefully moved into third gear. He had me stop and repeat the procedure two or three more times until I came to the end of the section. I was feeling pretty good as I came to a stop and looked to Daddy for approval.

He glared at me and then barked, “You've been driving, haven't you?” He must have thought I'd been practicing in somebody else's car. I quickly explained that my training was all done on the Ford.

    That was 60 years ago. I can still see the nod he gave me when he said, "Well, you did a good job."

    Don't put it off, do it now!

    Why do we spend so much time not doing the work we should do, or putting off small jobs that have piled up to create a big problem? Procrastinating, as putting things off like this is called, is in our character we have naturally since birth; we avoid dull or difficult jobs until it's too late to do anything else.

    "We often put things off although we know it will make life more stressful," says Dr. Steel, an authority on the science of motivation. "If these tasks were fun, we'd just do them now. We put off what is difficult or unpleasant, such as the paperwork that needs doing before leaving the office or cleaning the bits of your home that people can't see. But the fact is, the less people procrastinate, the more money they have, the better relationships they have, and the healthier they are." This is obvious when you look at the couples who don't argue about whether anyone has cleaned the kitchen, and the people who simply go for a run instead of endlessly rescheduling it in their heads.

    Of course, there are the rest of us, who feel the small jobs piling up around us daily. "We've evolved to respond to the moment, and not to set our sights too far in an uncertain world," Dr. Steel adds. "We are not set up to appreciate long-term rewards, whether it's the benefit of a four-year degree, doing exercise or dieting. We usually feel the cost now and the reward comes much later." According to Dr. Steel, we have two decision-making systems. They are the limbic, which is responsible for the short term, and the prefrontal cortex, which deals with the future. We bounce between long-term goals and short-term temptations, so we need goals that will translate our plans for the limbic system.

    Let's take the example of students' writing essays. They should set themselves targets and word counts per day. These are thus turned from seemingly endless tasks into something concrete with measured progress. Dr. Steel recommends such techniques, or "pre-commitments", adding that leaving you a month before the "deadline" makes it more likely a task will be completed. The benefit is that you'll avoid the embarrassment of not following up on something people are expecting you to do—telling everyone you are going to take up jogging makes you more likely to do so.

    Overcoming procrastination finally comes down to planning, which, if you're not careful, becomes procrastination in itself. But it is worth making sure you have everything in place. "Successful people don't pretend they don't procrastinate," Dr. Steel says. "People who pretend they have willpower are less successful." Instead, plan for procrastination: make your work environment a temple of productivity by cutting out what stops you paying your attention, so you can really focus on moving forward.

    Americans gave nearly $300 billion away last year. Do you know the reason? Beyond the noble goals of helping others, it is that giving will make them happier.

    It is a fact that givers are happier people than non-givers. According to the Social Capital Community Benchmark Survey, a survey of 30,000 American households, people who give money to charity are 43% more likely than non-givers to say they are "very happy" about their lives. Similarly, volunteers are 42% more likely to be very happy then non-volunteers.

    The happiness difference between givers and non-givers is not due to differences in their personal characteristics, such as income or religion. Imagine two people who are identical in terms of income and faith, as well as age, education, politics, sex, and family circumstances, but one donates money and volunteers, while the other does not. The giver will be, on average, over 40 percentage points more likely to be very happy than the non-givers.

    A number of studies have researched exactly why charity leads to happiness. The surprising conclusion is that giving affects our brain chemistry. For example, people who give often report feelings of euphoria, which psychologists have referred to as the "Helper's High". They believe that charitable activity produces a very mild version of the sensations people get from drugs like morphine and heroin.

    Of course, not only does giving increase our happiness, but also our happiness increases the possibility that we will give. Everyone prefers to give more when they are happy. Researchers have investigated this by conducting experiments in which people are asked about their happiness before and after they participate in a charitable activity, such as volunteering to help children or serving meals to the poor. The result is clear that giving has a strong, positive causal impact on our happiness, so does happiness on giving
