As speakers, the one thing that we want to happen when we give a speech is to use the importance of public speaking and be remembered. 

In order to make this happen, we will spend countless hours thinking about what  we want to include in our next speech. We will often think about how  other people have been able to reach out and connect with our audience  and sometimes we’ll decide that we want to do the same thing that they  did – we want to use their material in our speech. When we make a  decision like this, we are starting to travel down a dangerous road. 

If  we use too much of someone else’s material then we may run the risk of violating their copyright.
