Seeking the bubble reputation,
Even in the cannon’s mouth.

The term “bubble reputation” in William Shakespeare’s “The Seven Ages of Man” (As You Like It – Act II, Scene VII) refers to the fleeting and fragile nature of fame or glory. Like a bubble, reputation may appear attractive and valuable but is ultimately insubstantial and easily destroyed. It implies that people often take great risks or make significant sacrifices for something as short-lived and delicate as a bubble, highlighting the futility or vanity of such pursuits.
