Remember "I am..." is a powerful creative statement. It is a declaration. A declaration begins the process of creating. Be sure whatever follows "I am..." is indeed what you want in the now and to perpetuate into the future. Also, make your statements concise and precise. Put it in a nutshell. Do not add to what you want all the reasons why you cannot have it, (i.e., "I want to have a new car, but I can't afford it). Instead simply state what you want ("I want a new car.") with no qualifiers, not but, no because, clean and clear.
