List of key words?

Are there constant key words or phrases that I can write down to use or remember that can apply to many different circumstances? For instance: I love it when I hear you say “so what” or “not your problem” etc. I can’t think of others at the moment but so often you’ll say something repetitive that seriously hits the nail on the head every time! Does this make sense? If not, I’ll try and figure out a different way to explain 😀
