Happiness is like a cloud, if you stare at it long enough, it evaporates.

The line uses a simple natural image to warn against over-scrutiny of one’s own emotional state. Like a cloud that seems to thin and disappear when you fixate on it, happiness can feel fragile when treated as an object to be measured, verified, or held in place. The implied counsel is to experience happiness indirectly—through living, engagement, and presence—rather than through constant self-monitoring (“Am I happy yet?”). It also hints at the transient, weather-like quality of moods: happiness comes and goes, and trying to pin it down can paradoxically undermine it.
