An actor's life is endless. What did it mean?

An actor's life in a painting is an ancient poem from the Tang Dynasty poet Wang Zhihuan's "Climbing the Stork Tower." The meaning of this sentence was that once an actor entered the entertainment industry, he was destined to wander far away from his hometown and never be able to settle down. This sentence is often used to describe those who pursue their dreams. In the process of chasing their dreams, they constantly rush and work hard. No matter where they go, they will wander for the rest of their lives and never find a home.
