I believe love is why we're here on the planet and that ultimately it's our purpose for life. They say people who've had near-death experiences often report back that at the end of our lives we have a life review and we're asked one question, and that question is, how much did you love?

Like your weight set-point, which keeps the scale hovering around the same number, your happiness set-point will remain the same unless you make a concerted effort to change it.

Once you begin to understand and truly master your thoughts and feelings, that's when you see how you create your own reality.

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.

If you think about the times in life when you've been the most deeply fulfilled, they're the times that you've felt love. Whether it's watching a sunset, spending time with a pet or being with a partner with whom you feel an intensely deep connection.

The best way to keep relationships happy, healthy, and supportive can be summed up in one word: appreciation. What you appreciate, appreciates. When we demonstrate our appreciation for the support we receive from others, it reinforces that behavior and deepens our connection to them.

The fourth doorway is the Doorway of Openness located in our heart center. It has to do with being open to both giving and receiving love. It's not just about being able to give, but it's also about the ability to be open to receive. There's a certain vulnerability in receiving. When we truly take in and appreciate all of the gifts of life, then our hearts are truly open in love.
