Napoleon Hill said thoughts are things and I thought at that stage that it was some kind of hocus pocus. But if you really focus on something. I mean really focus on something and act as if it is going to happen then there is no option that what you have been thinking about will come to fruition.
For example, maybe you want to lose weight and you focus on that fact. Just by focusing on it, you will find you start exercising on more regular basis. You will find that you start eating the types of foods that you should be eating and not drinking the types of drinks that shouldn't be drinking.
This can work for anything in your life, your health, your career, your business, your relationships.
If you focus on it then it has not choice but to become what you want.
