Trust in your own greatness.
You are not this body you occupy, which is temporary and on its way back to the nowhere from which it came. You are pure greatness … precisely the very same greatness that creates all of life. Keep this thought uppermost in your mind and you'll attract to yourself these same powers of creation: The right people will appear. The exact events that you desire will transpire. The financing will show up. That's because greatness attracts more of its own self to itself, just as thoughts of inadequacy act upon a belief that ensures that deficiency will become your reality. Affirm the following to yourself over and over until it becomes your automatic inner response to the world: I come from greatness. I attract greatness. I am greatness.
Look for beliefs that contradict your status as a being of greatness.
Catch yourself in the midst of any utterance that reflects your belief that you're average. Silently speak warmly to that belief and ask it what it wants. It may think it has to protect you from disappointment or pain, as it probably did earlier in your existence. But with continued accepting attention, the feeling will always eventually admit that it wants to feel great. So let it! You're good enough to withstand the passing disappointments and pain that afflict life on this planet—but trying to protect yourself by believing that you don't embody greatness is overkill.
Look for these misbeliefs and give them the chance to transform to what they (and you) really want. Whatever you desire to become or to attract to yourself, make the internal shift from It probably won't happen for me to It is on its way! Then begin the process of looking for even minute evidence that what you desire is indeed on its way. It's crucial to keep this ancient axiom in mind: I get what I think about, whether I want it or not. So think about how fortunate you are to have greatness located within yourself. Now you can live the ultimate paradox: You can be greatness and be nobody, simultaneously.
