The greater is the difference between your present vibrational frequency and the frequency you would maintain were your desire to manifest, the greater is the perceived difficulty of manifesting that particular desire. For example, it would be perceived to be fairly easy to manifest a single dollar, but the more dollars you wish to manifest, the greater the perceived difficulty of manifesting the desire becomes.
In other words, the greater the difference between the way you presently feel and the way you would feel were your desire to manifest, the more difficult you will perceive the manifesting of your desire to be. Thus, each step made towards improving the way you feel so that you feel as if your desire has already manifested will result in your finding the desire becoming easier and easier to bring to fruition.
