The Happiness Advantage in combination with interaction design

”The Happiness Advantage” is a term created by psychologist Shawn Achor. It means that the brain processes significantly better if it is in a positive mindset than a negative one. This leads to more intelligence, creativity and the energy level rises.
The brain sees the world through a lens, which shapes our reality. By changing this lens people can become happier and therefore more successful.

Most people think if they work harder they will be more successful and if they are more successful they will be happier. But every time the brain experiences success they just change the goal of what success looks like. Success becomes a moving target. Therefore we need to invert our thinking. We need to be happy first and this will lead to success. Not the other way around.

So how can people achieve long-term happiness and therefore become more successful by using techniques of The Happiness Advantage in combination with interaction design?
