Happiness fuels success – not the other way around – says Shawn Achor in his book “The Happiness Advantage.” He says that research shows us when we raise somebody’s level of happiness first by deepening their optimism and deepening their social connection, every single business outcome we can test for improves. Productivity rises 31%, sales rise cross industry by 37%, and you’re 40% more likely to receive a promotion. Happiness is actually a precursor to greater levels of success, not merely the result of it.
