When we encounter an unexpected challenge of threat the only way to save ourselves is to hold on tight to the people around us and not let go.

Focusing on the good isn’t just about overcoming our inner grump to see the glass half full. It’s about opening our minds to the ideas and opportunities that will help us be more productive, effective, and successful at work and in life.

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.

You can eliminate depression without making someone happy. You can cure anxiety without teaching someone optimism. You can return someone to work without improving their job performance. If all you strive for is diminishing the bad, you'll only attain the average and you'll miss out entirely on the opportunity to exceed the average.

The absence of disease is not health.

One of the most powerful forces in human nature is our belief that change is possible.

For two minutes a day, think of one positive experience that's occurred during the past 24 hours. Bullet point each detail you can remember. It works, because the brain can't tell the difference between visualization and actual experience. So you've just doubled the most meaningful experience in your brain.
