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

Poorly planned and stressful vacations eliminate the positive benefit of time away. The less the stress, the more likely you will experience a positive benefit from the time off. A positive, well-managed vacation can make you happier and less stressed, and you can return with more energy at work and with more meaning in your life.

The research says that being successful doesn't automatically make you happier, but being happier - being more positive - makes you more successful.

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