Today's lessons are about happiness in life. And every day is today. So simplify. And dance. And reflect. And stop, collaborate and listen.

"Whoever is happy will make others happy, too." I couldn't find the true source of this quote, which has been attributed to Mark Twain at times, Anne Frank at other times. In any case, I believe it.

There is no way to happiness. Happiness *is* the way.

I also believe that true happiness comes from within. It's one of the most important values I have learned and continue to learn. Life, the universe, and everything regularly emphasize that lesson.

When it comes to true happiness, lessons are repeated until they are learned:

• Breathe deeply. Anyone can find happiness, writes Amy Lukima.
• The Happiness Project studied everyone from Aristotle to Oprah, and found you're not happy unless you think you're happy. Also, our days are long but the years are short, says Gretchen Rubin.
• Happiness is all around us, if we take time to see. Riding the bus changes your perspective, says Snob on a Bus blogger Jacki Carr.
• If life is a game, these are the ten rules for being a human being, according to Chérie Carter-Scott.
  
• There are twelve things happy people do differently, according to Jacob Sokol. (Thanks seablackwithink.)
• Life is like business. It's 20 percent what happens to you, and 80 percent how you choose to react.
• Nothing stays the same. Life regularly changes things up on you. Stroke of insight is Jill Bolte Taylor's inspiring TED Talk about starting over.
• Got all that? Great. Now roll up your sleeves for some lessons on how to quickly and easily improve your life, an anthology of lessons from my favorite posterous author, Eric Barker.
