On a cold morning in May, I received a fascinating email from a high school friend. inviting me to a 10-day all-female surfing adventure in Portugal. The offer was irresistible, and I instantly knew my answer was yes.

The trip seemed simple enough. Ten women, ranging from 30 to 45 years old, all strangers, will gather on the Portuguese coast to embrace the challenge of surfing the Atlantic waves.

As a travel enthusiast, I quickly sought permission from my boss for this once-in-a- lifetime journey.

Through my 33 years, I’ve observed a common adult tendency: we often limit ourselves to refining skills we already possess. There’s a certain pride in improving our expertise, becoming increasingly knowledgeable in our chosen fields, yet unintentionally, this focus often leaves other skills undeveloped and leads to neglecting other areas of potential growth.

Two days later, I arrived in Ericeira, a charming surf town, where I met my surfing group. Despite our different personalities and backgrounds, we were all united in a persistent desire to challenge ourselves, learn, tackle and grow.

The shores at Ericeira, where the beginners learn to surf, are shallow and covered with slippery rocks. They make for softer waves but are difficult to navigate (驾驭).

Guided by our amazing coaches, together, we faced the waves. Sometimes, it poured with rain, and the waves crashed around us, but we were still out there. And with every slip and fall, words of encouragement filled the air.

Honestly, I probably spent most of my days frozen to the bone, but that didn’t matter because a new level of genuine joy and personal achievement had been unlocked.

Learning a new skill taught me the humbleness that can come from doing badly at something new, and the pride that develops when you finally manage to grasp something you’ve been working on.

While surfing might not be my calling, trying it out inspired me to take more risks in life, to step outside of my comfort zone and to never stop believing in myself. You never know what you’re capable of if you don’t go out there and try.

Some people think if you are happy, you are blind to reality. But when we research it, happiness actually raises every single business and educational outcome for the brain. How did we miss this? Why do we have these social misunderstandings about happiness? Because we assumed you were average. When we study people, scientists are often interested in what the average is.

Many people think happiness is genetic. That’s only half the story, because the average person does not fight their genes. When we stop studying the average and begin researching positive outliers —people who are above average for a positive aspect like optimism or intelligence —a wildly different picture appears. Our daily decisions and habits have a huge impact upon both our levels of happiness and success.

Scientifically, happiness is a choice. It is a choice about where your single processor brain will devote its limited resources as you process the world. If you scan for the negative first, your brain really has no resources left over to see the things you are grateful for or the meaning embedded(嵌入) in your work. But if you scan the world for the positive, you start to acquire an amazing advantage.

I wrote the cover story for the Harvard Business Review magazine on “Happiness Leads to Profits.” Based on my article called “Positive Intelligence” and my research in The Happiness Advantage, I summarized our researched conclusion: the single greatest advantage in the modern economy is a happy and busy workforce.

A decade of research in the business world proves that happiness raises nearly every business and educational outcome: increasing sales by 37%, productivity by 31%, and accuracy on tasks by 19%, as well as a number of health and quality-of-life improvements.

How old is “old” ?

How old is “old” ?   【小题1】Two hundred years ago, you were old at 35. That was the average life then. At the turn of this century, as medical knowledge advanced, the average life span(长度) increased to 45. In 1950, 70-year-olds were really old. Today, a healthy 70-year-old is looking forward to many more active years.

So, how old is old? The answer is one you’ve heard many times, from all sorts of people. “You are as old (or young) as you feel!” The calendar(日历) simply tells you how many years you have lived.   【小题2】

Once an unknown author wrote , “ 【小题3】Nobody grows old by living a number of years; people grow old by giving up their goals.”

【小题4】Alice Brophy, when she was with the New York City commission for the Aging, said, “It upsets me when people say, ‘Gee, you look young for your age!’ What does that mean? Is there some model that you’re supposed to look a certain way at 65 and 75 and 85? You know you can die old at 30 and live young at 80.”

There are many wrong ideas about aging.   【小题5】Here are some of the more common ones. For example, most older people are in poor health, or older people are unable to change.
