Did you ever want to be like your dad when you grow up? Maybe have a job like his or learn his trade? Sam Dent has done just that. She's a horse master and works for her father, Steve Dent, in their family business in Hertfordshire, England, which trains horses and then works with them on movie and television production sets.

Sam has been riding horses and competing internationally since she was three years old. Now twenty-three, she and older brother Will train the horses to perform, and the actors how to ride and handle the animals. The actors in War Horse, including Benedict Cumberbatch, Tom Hiddleston, and Patrick Kennedy "weren't the best when they turned up," she told The Telegraph newspaper, "but they all took to it."

Still as Dent Horse Master, training and caring for the Dent horses is Sam's most important job. It's hard to say no to what movie directors want, she says, because they "don't always like it. But ultimately we're the ones in charge of the horses."

Learning how to fix things is an important part of growing up and becoming independent. And learning how to fix things, especially things most people don't want to touch, can turn into a good career. Just ask Charlie Mullins.

Mr. Mullins grew up in a rough part of London. After leaving school when he was 15, he went to work, following the advice from a childhood mentor. He finished a four-year apprenticeship in plumbing, then bought an old van and some old tools. He was ready to fix broken toilets, sinks, showers—anything his skills and hard work could get running again.

He started Pimlico Plumbers in 1979. Because he didn't like seeing rusty old trucks and plumbers in grease-stained clothes, he decided his plumbers would drive bright blue vans and wear clean uniforms. Today Pimlico has over 200 workers, 160 trucks, and is London's largest independent plumbing and service company.

But Mr. Mullins hasn't forgotten how he got his start. Pimlico employs its own apprentices and participates in the Just the Job work placement program of the Prince's Trust. "My early experiences as an apprentice shaped my life and success," he said in a startups.co.uk interview. Now he's helping young people learn how to pick up a wrench and get that leaky loo back in business.

Suppose you found a really beautiful old painting, but there were dirty fingerprints all over the canvas, and a rather large tear. You wouldn't run for the dish soap and a bucket of water to fix it. Instead, you'd need to find an art restorer, someone who knows just how to clean and mend paintings without damaging them further. Simon Gillespie has been fixing old, and new, paintings for over 30 years. He has his own restoration business, Simon Gillespie Studio, on Bond Street in London, where he and six team members work on paintings that may be covered with old varnish, dust, dirt, along with previous attempts to "fix" cracks and chips. Even modern paintings can be damaged or torn and need restoration. Finding the right solvent to take off old varnish can sometimes take up to 40 different tries with various formulas, but once the dirt, gunk, and varnish are gone, restoring a picture to its original condition also means sitting very close to the canvas and working on one very small bit or section of the painting at a time. Bit by bit, the restorer moves across the painting, mending tears and daubing on new paint where the old has chipped off or been cleaned before. His team uses modern pigments to touch up problem areas and fill the holes, devoting "hours of patient work with a tiny, fine pointed brush made from Russian sable to retouching the damage," as he told Bond Street Magazine. Mr. Gillespie decided to become a restorer when he visited a restoration studio in Mexico City. After two apprenticeships, studying chemistry, and learning as much art history as he could, he was ready to start his business. Today he does restorations for galleries, auction houses, and private collectors. But after working on tiny patches of a painting for hours at a time, what does he do when he has free time? "Outside of work, I enjoy climbing mountains," he says, "the higher, the better!" in this episode, Hope interviews Simon Gillespie, art restorer.

If you've ever shared your pictures on your phone or know someone who has, you probably know about Instagram, the social-network where members post pictures and videos. Marne Levine is the Chief Operating Officer (COO) of Instagram – that means she's responsible for the company's business operations, like marketing, development, communications, and recruiting. She's also worked for Facebook and was part of the Obama and Clinton administrations' economic teams. And, of course, Marne is on Instagram and has some pretty amazing photos from her work and travels around the world – you can follow her @marnelevine!

In this Episode, Olivia interviews Marne Levine at Instagram headquarters in Menlo Park, California.

Did you know that some 22 billion times a day, someone sees the Facebook Like button?! That little button is just one small element of Facebook, but those elements really matter, says Margaret Gould Stewart. She's Vice President of Product Design at Facebook, meaning she uses visual design to help people get the most out of the giant social networking site. Margaret has also worked at Google and You Tube, and at Facebook, her team is designing for a worldwide audience, a big and complicated job when you consider how many different people in the world with use Facebook. Through good visual design, she helps make Facebook accessible to absolutely everyone, including people who may have a hard time even connecting to the Internet. One fascinating part of coming up with new elements for this huge global audience, she says, is finding out that people use the designs in exciting ways that she, and other designers, never expected!

In this Episode, Mason interviews Margaret Gould Stewart at Facebook headquarters in Menlo Park, California.

Do you ever make drawings on your homework? Or doodles on little pieces of paper? So did Liz Pichon when she was a kid, and today, she's a famous author.

Liz Pichon writes the Tom Gates books — the ones with the crazy covers and cool stories — that have sold more than a million copies. To put that into perspective, if you piled up all the copies people have already bought of Liz's books, the stack would be taller than a 25-story skyscraper! Liz has also also written and illustrated My Big Brother Boris, My Little Sister Doris, and Beautiful Bananas. Her books have won four big awards so far, and been translated into 37 languages. In this Episode, Finn interviews Liz at a London book shop!

Sir Ken Robinson would like you to know that even if you think you aren't good at anything, you still have talents – and probably lots of them. "We're all born with immense, natural, creative abilities," he said in an interview with National Public Radio. But somewhere during our days in school, we learn that being 'creative' only means being good at things like art or music or writing poetry, even though many adults – from scientists and historians, to cooks and construction workers – are creating and exploring new ideas every day. Discovering what you like to do and then figuring out how to learn to do it well means you will be able to create your own life – and recreate it when you want to change. Taking chances and experimenting may mean goofing up or making mistakes, he says, because if you're not willing to be wrong, you won't come up with anything new or original. A quiet kid who spent years recovering from polio, a dangerous disease that left him wearing leg braces, Sir Ken spent most of his time reading and watching from the sidelines. Then when he was a teenager, despite being terrified, he agreed to be part of a family musical production. To his surprise, he discovered that he liked being on a stage, talking and acting. He found that his talent is communicating and working with people, which he's done as a writer, researcher, adviser, and teacher. Today, he works with schools, government organizations in the United States and Great Britain, and many private and public organizations that want to improve education and promote the arts. What's most important for kids to know as they go through school? Explore your own talents, find what you're good at, he says, and know that you can and will create your own life, by yourself. Respect where you come from but don't be locked into that one place. And be prepared – but not afraid – to be wrong! In this episode, Mason interviews education expert Sir Ken Robinson at the Bob Baker Marionette Theatre in Los Angeles.

Imagine it's 1986 and you have to do a school report on lions. You may have seen one in a zoo or watched a TV nature show, but you'll probably have to go to a library and look for an encyclopedia with a story on lions. Maybe you can also photocopy a picture for your report.

Now imagine your report is due this Friday. Your assignment will be a lot easier than thirty years ago, thanks to Jimmy Wales. Today, you'll get on the Internet, search for "lions," and instantly find thousands of entries. At or near the top of the list will be the Wikipedia page on lions, with pictures and links to all sorts of other lion-related information, all for free.

Mr. Wales was an American financial trader, but he wanted to set up an Internet encyclopedia that would be free for everyone. He and his colleagues couldn't write all the entries themselves, so after a few attempts, Mr. Wales decided to make Wikipedia "open source" —where the readers write, edit, and add more information to the entries themselves, supervised by the Wikipedia staff.

Wikipedia launched in January, 2001. Today it is the world's largest encyclopedia, with over 38 million articles in 250 different languages. It's part of the Wikimedia Foundation, along with fifteen other Wiki websites. The Foundation is non-profit which means Mr. Wales hasn't become a billionaire. He's just the biggest information guy in the world!

When Jane Goodall was a young woman, she moved from England to Africa, to study the chimpanzees of Tanzania. She studied chimps by living with them and came to know them as individual creatures. Her methods changed the way scientists now observe other creatures' behavior.

One of Dr. Goodall's most important discoveries was that other animals make and use tools, just like humans do. She watched the chimps take pieces of grass and poke them in ant holes. When the ants climbed on the stalk, the chimps pulled the grass out and had a snack of ants!

In 1986, after years of research, Dr. Goodall left Tanzania to begin working to save chimpanzees, traveling about 300 days every year to visit schoolchildren and speak to groups around the world.

She is a passionate advocate for all animals and emphasizes the interconnectedness of all life, while working with many different charities and animal-welfare groups. She founded the Jane Goodall Institute which supports the continuing research in Tanzania and the effort to protect chimpanzees and their habitats. And she started a global organization for young people called Roots and Shoots, encouraging young people to get involved in changing the world for the better.

Would you want to live for a thousand years? Or forever? Aubrey de Grey is a gerontologist, a scientist who studies the ways people grow old and why this happens. He is working on how to keep people's bodies healthy and running right, so they can live for maybe hundreds of years. Most scientists don't think it's possible to stop people from getting old. But Dr. de Grey says that even if we can't do this today, we should keep studying and learning. In the future, we may be able to live healthy for years and years. And years!

When he's not studying aging, Dr. de Grey loves to go punting and is quite good at it himself. A punt is a flat-bottomed boat which the punter pushes along the canal or river with a long pole. In this Episode, Aubrey invites Bradley on a punting trip in Cambridge, England, home of Cambridge University, one of the oldest and most important universities in the world, and also one of the world's best spots for punting!
