"If your so-called friends urge you to do anything you know to be wrong, you be the one to make a stand for the right, even if you stand alone.Have the moral courage to be a light for others to follow."- Thomas S. Monson

This quote means that  don't do something you don't want to do. Do not be forced to obey people when they are invocating you into doing something bad.You have to stick up and speak what you think. Don't just do what everybody does. When you start to do things other people you are just an imitation of them.Everyone is unique in your own way. You don't have to do something you don't like because they are forcing you. You have different thoughts and you will not like to do something you don't like.For example if someone jumps off a cliff will you do it too?No you will not because you will not sacrifice your life for someone's else's.You don't have to do everything everybody else does just so you can fit in.Everyone is different in their own ways and you will stand out.You will like to be that person who stands out from the rest.The one who is known for doing something differnet in their life then just copy or imitate what everybody else is doing.
