Study after study shows that happiness precedes important outcomes and indicators of thriving.

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

Happiness is actually an individual choice, even in the midst of negative circumstances. It's not something our employers can give to us, though they can limit and influence that choice.

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.

We not only need to work happy, we need to work at being happy.

The fastest way to disengage an employee is to tell him his work is meaningful only because of the paycheck.

When a manager openly expresses his faith in an employee's skill, he doesn't just improve mood and motivation; he actually improves their likelihood of succeeding.
