The law of attraction means that everything that happens to you—good or bad—you attract to yourself. Lisa describes it as if you're placing an order. "If you were at a restaurant and you ordered something, you fully expect it to come served that way. That's how the universe is. You're putting out orders—consciously and unconsciously," Lisa says. "So if you say, 'I'll never have a great relationship,' you just placed an order."

Jack says everything you focus on can have an effect on your life—from books to magazines to thoughts. "All of that affects how we feel, and the feelings actually send out a wave into the universe, and anything that's vibrating in a similar level gets attracted into our life," Jack says.

"Most people focus on how it is. We talk about our current reality—'I'm in debt. I'm overweight. I'm not happy. I'm sad. The world's not working. We're at war,' whatever. And the more you think about that and focus on that and talk about it, the more you attract that [negativity]," he says.
