You have to train your brain to be positive just like you work out your body.

As we got more interested in time management and productivity, we lost the individual, and with that individual loss, we lost happiness as well. So I think the world has actually been malnourished as we've focused so much on productivity and ignored happiness and meaning to our own detriment.

Habits are like financial capital – forming one today is an investment that will automatically give out returns for years to come.

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.

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.

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.

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