Fair Use

I really do not understand the full definition of fair use. All I know is if you are using someone else's work, make sure you credit their work. Personally, I like to come up with ideas on my own instead of using the work of another person. It would be a lot easier on myself and everyone else. If you happen to get sued for libel, make sure you can prove that you are telling the truth with the right facts to support your work.
