Helen Russell

Having spent the last few years in Denmark uncovering the secrets of the happiest country in the world, Helen Russell knows it's time to move back to the UK. She thinks. Maybe. Or maybe that's a terrible idea. Like many of us, she suffers from chronic indecision and a fear of change. So she decides to give herself a year for an experiment: to overhaul every area of her life, learn how to embrace change and become a lean, mean decision-making machine.

When she was suddenly given the opportunity of a new life in rural Jutland, journalist and archetypal Londoner Helen Russell discovered a startling statistic: the happiest place on earth isn't Disneyland but Denmark, a land often thought of by foreigners as consisting entirely of long, dark winters, cured herring, Lego and pastries. What is the secret to their success? Are happy Danes born or made?

"The dirty little secret about most organizing advice is that it's written by organized people," says blogger, speaker, and decluttering expert Dana K. White. "But that's not how my brain works. I'm lost on page three." Dana blogs at A Slob Comes Clean, chronicling her successes and failures with her self-described "deslobification process". In the beginning she used the name Nony (short for aNONYmous), because she was sharing her deep, dark slob secret. Now she has truly come clean - with not only her real name but the strategies she has developed.

Bryony Gordon was not a runner. A loafer, a dawdler, a drinker, a smoker, yes. A runner, no. Yet somehow, as she began to recover from the emotional roller coaster of laying her life bare in her mental health memoir Mad Girl, she started to realise that getting outside, moving her body and talking to others for whom life was also an occasional challenge might actually help her.

No skill is more important in today's world than being able to think about, understand, and act on information in an effective and responsible way. What's more, at no point in human history have we had access to so much information, with such relative ease, as we do in the 21st century. But because misinformation out there has increased as well, critical thinking is more important than ever. These 24 rewarding lectures equip you with the knowledge and techniques you need to become a savvier, sharper critical thinker in your professional and personal life.

The world has reached unprecedented levels of wealth, but while we have succeeded in getting richer, we have failed in getting happier. While many people live lives of quiet desperation, a few people find themselves at the very top of the scale when it comes to happiness. Their behaviour is different. Their outlook is different. Their priorities are different. What can we learn from the world's happiest people?

Meet the Hunter family: Adam, Kate, and their children, Hal and Charlotte. And Prince, their black Labrador. Prince is an earnest young dog, striving hard to live up to the tenets of the Labrador Pact (Remain Loyal to Your Human Masters, Serve and Protect Your Family at Any Cost). Other dogs, led by the Springer Spaniels, have revolted. As things in the Hunter family begin to go badly awry - marital breakdown, rowdy teenage parties, attempted suicide - Prince's responsibilities threaten to overwhelm him and he is forced to break the Labrador Pact.

Lee Lipsenthal had a charmed life: married to the love of his life, the proud father of two remarkable children, working as medical director of the Preventive Medicine Research Institute. In his personal relationships and with his patients, Lee was committed to living his life fully and gratefully each day. The power of those beliefs was tested in July 2009, when he was diagnosed with esophageal cancer, leaving him with a 90 percent chance of dying within five years.

What Does it mean to feel truly alive? Aged 24, Matt Haig's world caved in. He could see no way to go on living. This is the true story of how he came through crisis, triumphed over an illness that almost destroyed him and learned to live again. A moving, funny and joyous exploration of how to live better, love better and feel more alive, Reasons to Stay Alive is more than a memoir. It is a book about making the most of your time on earth.

Based on seven years of ground-breaking research and hundreds of interviews, I Thought It Was Just Me shines a long-overdue light on an important truth: Our imperfections are what connect us to each other and to our humanity. Our vulnerabilities are not weaknesses; they are powerful reminders to keep our hearts and minds open to the reality that we're all in this together.

Michelle McGagh has been writing about money for over a decade. You'd think that would make her a whiz with her own cash, right? Wrong! Spending with abandon and ignoring bank statements were her modus operandi. Just because she wasn't in serious debt apart from her massive London mortgage, she thought she was in control. She wasn't. Something needed to be done ,but rather than cut back here and there, Michelle's approach was more radical.

Imagine the twisted evil twins of Sherlock Holmes and Doctor Watson and you have the dangerous duo of Professor James Moriarty - wily, snake-like, fiercely intelligent, terrifyingly unpredictable - and Colonel Sebastian Basher Moran - violent, politically incorrect, debauched. Together they run London crime, owning police and criminals alike. When a certain Irene Adler turns up on their doorstep with a proposition, neither man is able to resist.

There are three things you should know about Elsie. The first is that she's my best friend. The second is that she always knows what to say to make me feel better. And the third...might take a little bit more explaining. Eighty-four-year-old Florence has fallen in her flat. As she waits to be rescued, Florence wonders if a terrible secret from her past is about to come to light; and, if the charming new resident is who he claims to be, why does he look exactly like a man who died 60 years ago?

Eating is an indispensable human activity. As a result, whether we realize it or not, the drive to obtain food has been a major catalyst across all of history, from prehistoric times to the present. Epicure Jean-Anthelme Brillat-Savarin said it best: "Gastronomy governs the whole life of man."

The megatalented creator of Grey's Anatomy and Scandal and executive producer of How to Get Away with Murder chronicles how saying yes for one year changed her life - and how it can change yours, too.
