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.

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?

When you forgive, you heal your own anger and hurt and are able to let love lead again. It's like spring cleaning for your heart.

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.

Love isn’t just something we feel for others, it’s who we are. Though we usually think of love as a stream of emotion flowing between two people, love is more like an ocean that’s inside and all around us. Instead of walking around with a little cup, begging for a few drops of love from others, recognize that you’re the huge ocean of love.

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-.

So the difference between most books about love and Love For No Reason is that traditional love books focus on love as a stream of energy between two people, whereas this book focuses on love as a deep state of being that you can live in no matter what's going on in your life.
