In my point of view, the secret is that you are what you think. You become what you think about.
We are creatures of habit. We tend to follow the picture in our minds created by our parents, our neighborhood, our town and the part of the world from which we come. But we don’t have to. We each have a mind of our own, capable of imagining life the way we want it. Start imagining your life the way you want it. Create a picture in your mind and think about that picture steadfastly all day long. Believe in it. You will start making different choices in line with your picture. You will take small steps in the right direction. You will also encounter obstacles. Don’t let these obstacles stop you. If you hold your picture of the life you want solidly in your mind, you will eventually create that life.
