Is there a website where I can check to make sure any quotes I make up is not copyright infringement?

you can either google the quote to make sure someone hasn't said it, or you can just say the idea in your own words. Take for instance the phrase: everything changes. People have said this since the beginning of time. You think father time is going to judge you for "copy right infringement?" Just speak your mind, if it coincides with a famous philosopher, more power to both of you.
