Here's the article by Kate Bratskeir that summarizes some great points from Seligman's talk:
Here are some of the 16 things Bratskeir says happy people do (pasted right from her article with lots of good links to further information):
They try to be happy.
Yep -- it’s as simple as it sounds: just trying to be happy can boost your emotional well-being, according to two studies recently published in The Journal of Positive Psychology. Those who actively tried to feel happier in the studies reported the highest level of positive moods, making a case for thinking yourself happy.
They are mindful of the good.
It’s important to celebrate great, hard-earned accomplishments, but happy people give attention to their smaller victories, too. “When we take time to notice the things that go right -- it means we’re getting a lot of little rewards throughout the day,” Susan Weinschenk, Ph.D. told The Huffington Post in May. “That can help with our moods.” And, as Frank Ghinassi, Ph.D. explains, being mindful of the things that do go your way (even something as simple as the barista getting your coffee order right) can make you feel a greater sense of accomplishment throughout the day.
They appreciate simple pleasures.
A meticulously swirled ice cream cone. An boundlessly waggy dog. Happy people take the time to appreciate these easy-to-come-by pleasures. Finding meaning in the little things, and practicing gratitude for all that you do have is associated with a sense of overall gladness.
The experience of sacred time provides a time apart from the “profane time” that we live most of our lives in. A daily period of meditation, a weekly practice of lighting Sabbath candles, or attending worship services, or an annual retreat in an isolated, quiet place of solitude all of these are examples of setting time apart from the rush of our everyday lives. Periods of rest and respite from work and the demands of daily life serve to reduce stress, a fundamental cause of chronic diseases that is still the primary causes of death in Western society. Transcendent spiritual and religious experiences have a positive, healing, restorative effect, especially if they are “built in,” so to speak, to one’s daily, weekly, seasonal, and annual cycles of living
