The physical benefits of laughter are well documented. Laughter decreases stress hormones, boosts the immune system and raises the heart rate, bringing more blood and oxygen to the brain. It also increases the level of alertness and memory as well as the ability to learn and create.

Benefits for the Office

It makes sense that all that extra brain power and relaxation would lead to enhanced performance at work. But laughter has other benefits around the office, which include:

Stronger Teams. Laughter breaks down barriers, builds relationships and allows for better communication among coworkers. People with a sense of humor often have the ability to deal effectively with people and work issues, and they keep the severity of problems in perspective.

Psychologist, clinical researcher and bestselling author Martin Seligman has spent 25 years studying optimism and pessimism. In his book, Learned Optimism, he states that pessimistic thinking can undermine not just our behavior but our success in all areas of our lives.

“Pessimism is escapable,” he writes. “Pessimists can learn to be optimists.”

By altering our view of our lives, we can actually alter our lives, he says. First, he says we must recognize our “explanatory style,” which is what we say to ourselves when we experience a setback. By breaking the “I give up” pattern of thinking and changing our interior negative dialogue, we can encourage what he calls “flexible optimism.” He believes that focusing on our innate character strengths (wisdom, courage, compassion), rather than our perceived failures boosts not just our moods, but our immune system. Research has shown that optimistic people tend to be healthier and experience more success in life; therefore, he encourages parents to develop the patterns of optimism in their children.

As Suzanne Falter-Barns says in her book, How Much Joy Can You Stand?, if we begin to nurture and pursue our dream, if we can manage to leap off the cliff and trust ourselves to fly, we will experience a fine, effortless joy like nothing else. “It may take a while to wade through all your resistance, fears, misperceptions and basic disbelief in yourself,” she says. “It may take far longer than you think it should. But if you can just keep going through the process, and trust yourself in a basic way not attempted before, the joy will be yours.” Test your joy quotient with this quiz.

1. Creativity doesn’t just belong to artistic types living in loft studios. It belongs to me and to every human. I AM creative!

2. I think of myself as someone who doesn’t just want what I want, but as someone who is going to get it.

The real trick, however, is how to bring joy to anything you do. Doing so can transform the mundane into the enjoyable and let loose incredible energy for all you put your attention to. The secret: creativity. Feeling creative and playful helps us bust through resistance, fear, boredom and disbelief on our way to an engaged satisfaction. Test your joy quotient with this Self-Quiz.

1. Creativity doesn’t just belong to artistic types living in loft studios. Work is a place I frequently exercise my creativity.

2. I think of myself as someone who doesn’t just want what I want, but as someone who is going to get it. It’s just a matter of figuring out how.

3. I keep blank notebooks in several places for jotting down my ideas and inspirations, and a tape recorder for recording observations.

4. No matter how “uncreative,” sensible, logical and otherwise unimpulsive I might consider myself, if I have a pressing idea—a core desire—I’m going to express it.

When you were little and the teacher asked what you wanted to be when you grew up, you surely didn't answer "miserable!"

At every stage in life, unhappiness is not a state to which we aspire. But with the economy rolling downhill, the vision of our own prosperity can seem like a tiny, inflatable raft in an ocean of fear. In such unstable times, the pursuit of happiness can feel like a taunt rather than an inalienable right.

Still, it's worth the effort. Emerging research shows that while trauma has a profound impact on the brain, the brain is not as hard-wired as previously thought. We can learn to be happier. In fact, the most popular class at Harvard University is one in which students learn to train their brains to cultivate what instructor Tal Ben-Shahar calls the ultimate currency: happiness.

In study after study, researchers have found that those who have friends are less likely to become disabled and more likely to recover if they do suffer a period of disability. Further, people with fewer friendships are more likely to have a heart attack and to die afterward while people with more social contacts are less likely to suffer cognitive decline.

The message from all this research: If friends are gifts we give ourselves, it’s good to be generous.

Why are friends so good for us? Health-wise, friends encourage us to do what’s good for us: eat better, drink less, exercise and seek medical care when we need it; friends listen to us when we need to let off steam and cheer us up when we’re down. We stress less when we have friends who support us and help us along the way.

Our lives are inspired by people who have endured catastrophic life experiences and emerged the victor, rather than the victim. Helen Keller, Mahatma Ghandi, Nelson Mandela, and Elie Weisel are some of the more familiar names, but many of us have personally known individuals who have come through the other side of a wrenching experience with grace and humility.

If we could ask each one—the famous and the familiar—“What got you through your crisis?” in all likelihood the responses would be similar. One by one, they would describe inner resources that enabled them to survive. Brian Luke Seaward, author of Stand Like Mountain, Flow Like Water, calls those qualities “the muscles of the soul.” Courage, faith, humor, patience, compassion, imagination, humbleness, forgiveness, intuition, creativity, optimism, honesty, and love.

It is in exercising those muscles that the health of the human spirit is maintained. And the fitness of the spirit is vital to our total well-being.

A Great Day is one of those days where things go so right, when we accomplish something that makes us feel really good about ourselves, and we connect with people in meaningful ways. A day we experience joy.

Of course, not every day can be a great day, but the following 10 tips can transform what might be an ordinary day into something that verges on great.

1. Start off with a plan. Ask yourself what one thing you can do that will build toward creating a great day.

2. Be mindful. Throughout the day be present in all that you do.

3. Spend time with those you love. If you can’t be together in person, call or write a letter or email. Connect.

“Most of the time, we are lost in the past or carried away by the future,” says Thich Nhat Hanh, a Buddhist monk and poet. Staying in today will bring a more peaceful, joy-filled life. Try these ten ways.

1. Be present in the present. Pay attention to the details: Notice the food you eat, the sun on your back, the quality of the light, literally stop to smell the roses.

2. Make a list of what you want to accomplish today. List only the portion of a major project that can be completed today. Include pleasures as well as tasks.

3. Concentrate on the task at hand, not the outcome. Give it your best, knowing there is no perfect.
