Andre Averbug said this quote

The problem with happiness is that it’s a difficult thing to detect. It’s discreet and serene by definition. Just when you think you’ve found it, it’s likely just a spark of euphoria, as quick and fleeting as fireworks. Human beings are therefore doomed to feeling happy without knowing it or experiencing brief and unstable glimmers of euphoria. There aren’t many people who have the tantric ability to fully experience happiness, detached from the bliss of euphoria.
