Remember, each emotion indicates how much Energy you are summoning because of your desire, and how much of that summoned Energy you are allowing because of the predominant thoughts and beliefs that you currently hold relative to that desire. If you are feeling strong emotion, whether positive or negative, that means your desire is powerfully focused and you are summoning a great deal of Source Energy toward your desire. When your strong emotions feel bad - like depression, fear, or anger - that means you are offering resistance to your desire. When your strong emotions feel good - like passion, enthusiasm, expectation, or love - that means you are offering no resistance to your desire, so the Source Energy you have summoned through your desire is not being challenged vibrationally by you — and you are currently allowing the unfolding of your desire!
So it seems obvious that the perfect creative situation is to really, really want something that you truly believe is possible. And, when that combination of desire and belief is present within you, things will quickly and easily unfold in your experience. But when you want something that you do NOT believe is possible; when you hold a desire for something that you do NOT expect - although a strong enough desire can override a weaker belief - it does not unfold easily, for you are not letting it into your current experience.
