This will not get you a job.
This is good; expound on it. State facts to back it up. How long have you worked for your current employer? Tell a story about a time when you went out of your way to assist a coworker.
This is way too general. What does it mean to be a good worker? Don't say "You want me because I'm good," say "You want me because these are the things I've done that display my goodness."
