"If it is not right, do not do it; 

If it is not true, do not say it."

-Marcus Aurelius 

If You say something that is not true, you are choosing the wrong. If you do something that is not right, you are choosing the wrong. Choose the right, that path will lead you to success. If you do something that you know will bring you repercussions, don't do it. For example, your friends invite you to a party and you go. People are smoking and drinking alcohol at the party, they offer you some and what do you do ? You say no. You're underage and that'll only get you into trouble. Don't do things that'll get you in trouble. If something is not true don't say it. Thats lying and that'll only cause problems. Don't lie. For example if you and your friend stop talking don't go around saying things that aren't true.That's going to cause so much drama. But at the end the choice is yours. Make sure you choose the right because you can never go wrong when choosing the right.
