Time flies like an arrow意思

"Time flies like an arrow" is a popular English idiom that means time passes quickly and relentlessly, just as an arrow flies swiftly and directly through the air. It suggests that time moves forward at a steady pace, much like an arrow travels towards its target, and that it does so with great speed. This phrase is often used to express a sense of urgency or to remind people that time is precious and should be used wisely.
