These are the 3 magic keys to living your life with integrity:

1. Have the courage to say no.
2. Have the courage to face the truth.
3. Do the right thing because it is right.

I think this means is that you should not be afraid to do whats right for you and say what's right for you. This is saying that you should be able to say no to the things that are not good for you. Like if someone offered you a cigarette or a beer than you should be able to say to them. You have to own up to the things they did and not lie about it. Like if someone is saying the truth about something you did than you have to up and say you did do that. You have to choose the right and not do the wrong thing. You have to do what is best for you, like if someone told you to do something wrong then you should choose the right and not do it.
