That which you think about is happening to the extent you have given it your attention, whether or not you are aware of the way it is unfolding in your life experience. If you have given it your attention, you can be certain that it is happening in your life experience to some degree, and the more do you give it your attention, the more will it unfold in your life experience.
Since your life experience equals the vibration you are emitting, and the vibration you are emitting matches the sum of your thoughts, every thought you think has to manifest. Thus, when you give your attention to your desires, your desires have to manifest as a result, and the more attention are your desires given, the more will your desires manifest in your life experience.
