These are lines from the movie, "Spider-man." The hero is looking for a job and his friend's father offers him to help to find a new job. But the hero turns down the offer politely and says, "No,I couldn't accept it, sir. I like toearn what I get." I'd like to know the meaning of "I like to earn what I get." and also want to know whether the line is often used and if so , in what kind of situations you use the line.
