2. Believe.
When you're telling a lie, it's key to seem authentic. If it doesn't feel real to the person you're lying to, then.....sorry my dude. For your lie to seem like a truth, you have to BELIEVE. Believe that your lie is REAL. Believe that your lie is the TRUTH. You have to make yourself believe that you are telling the truth. If you think you're being truthful, than others will as well. You obviously can have some little knowledge that this is a lie so you can be prepared to make more lies as the situation continues. But if you don't believe, no one else will.
