How do you make stubborn people listen?

Most of the time you should not try to make stubborn people listen, you just say "okay I'm done" and do not be friends with them anymore( Well you don't have to say I'm done but I'm just saying just don't be friends with them anymore). but if they are a really good friend that you do not want to give up just try to be nice and correct them, do not say they are wrong because that will make them angry so just say what would be a better idea and try to explain it to them.
