..the more you believe in your own ability to success the more likely it is that you will.

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 not the belief that we don't need to change; it's the realization that we can.

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.

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.

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

The best leaders are the ones who show their true colors not during the banner years but during times of struggle.
