Many people spend years believing happiness comes after success.

The common mindset sounds familiar: “I’ll be happy when I get promoted,” “I’ll feel better when life becomes easier,” or “Once everything works out, I’ll finally relax.” But strangely, even after reaching milestones, many still feel stressed, overwhelmed, or emotionally exhausted.

What if the order is wrong?

What if happiness is not the reward for success, but actually the reason success becomes easier?

That is the powerful idea explored in The Happiness Advantage by Shawn Achor.
