I interviewed 100 happy people - I call them my Happy 100 - and I learned amazing ideas and techniques from them that I began integrating into my life. I put them into practice - and they worked! I went from a D+ in happiness to an A-.

What would our lives be like if we could all be happy no matter what?

When you're happy for no reason, you're unconditionally happy. It's not that your life always looks perfect - it's just that however it looks, you'll still be happy.

When you're Happy for No Reason, you bring happiness to your outer experiences rather than trying to extract happiness from them. You don't need to manipulate the world around you to try to make yourself happy. You live from happiness, rather than for happiness.

Taking ownership of your happiness has two aspects: Accepting that being happy is up to you and that you have the ability and power to be happier by changing your habits. Taking "response-ability": responding to all the events in your life in a way that supports your happiness.

In an experiment by Dr. Robert Emmons at the University of California–Davis, people who kept a ‘gratitude journal,’ a weekly record of things they felt grateful for, enjoyed better physical health, were more optimistic, exercised more regularly, and described themselves as happier than a control group who didn’t keep journals.

One of the things that happens when we're feeling more love and care is that we go into what's called "heart rhythm coherence," which you can actually measure and monitor on a computer screen. It's also possible to train yourself to go into heart rhythm coherence at will.
