Sergio is disappointed at life. So he visits his good friend, Julia.

　　Sergio: Life has given me an extra serving of trouble.

　　Julia: Your life isn't so bad.

　　Sergio: It isn't so good. When I walk outside I see a lot of unhappy faces. It concerns me. So many people, so many lives, but how many are truly happy?

　　Julia: Most people are not happy. If they are it is inside them.Sergio: If their life is so bad then why don't they change it? There is very little to stop them from changing their life.Julia: There is one big block.

　　Sergio: What is that?Julia: Themselves. People degrade their own lives.Sergio: A second grade life is deplorable. People can accept such bad things?

　　Julia: It's a habit. They get used to it and then forget how to change it. They even feel comfortable with it.

　　Sergio: Someone once said that humans only use less than 10% of their brain potential. Ten percent. If 10% can create such a world, imagine if people used 20%.

　　Julia: We operate far below our potential. The smart people use the 10%. The average are probably much lower.

　　Sergio: I wonder if there is a key to unlock that stored potential. Who knows what we could accomplish.

　　Julia: It is unlimited. Our ability is limited by our mind.Sergio: Maybe our brain is the door.

　　Julia: Or a heavy prison gate.
