The contents of the glass don’t matter; what’s more important is to realize there’s a pitcher of water nearby. In other words, we have the capacity to refill the glass, or to change our outlook.

Happiness is such an incredible advantage in our life. When the human brain is positive, our intelligence rises, we stop diverting resources to think about anxiety.

Waiting to be happy limits our brain's potential for success, whereas cultivating positive brains makes us more motivated, efficient, resilient, creative, and productive, which drives performance upward.

By changing our mindset and habits, we can actually dramatically change the course of life, improve intelligence, productivity, improve the quality of our lives, and improve every single education and business outcome.

Happiness is the joy we feel striving after our potential.

I've worked with farmers in Zimbabwe who've lost their lands. I've worked with people in Venezuela, under threat of kidnappings, whose external world is unstable. But they have very strong social connections with their family and friends. And as a result, they're able to maintain a greater level of happiness and optimism than I've seen from bankers, consultants, or salespeople who are on the road all the time, who follow jobs separated from their families, and, as a result, find themselves missing out on the happiness that comes from those very connections that they severed.

Our daily decisions and habits have a huge impact upon both our levels of happiness and success.
