A Universal Law is that your will cannot be crossed: not by another person nor by your Source Energy. Therefore, if you will hold a belief that something cannot be, then it will not.

Ask yourself, what am I desiring in my life and do I hold beliefs that will not allow this? Am I truly unwilling to allow this into my life?
The Law of Attraction abides by your energy. If your energy is unwilling, even if the unwillingness is buried deep down in your beliefs, then your energy will not truly flow in the direction of what you wish to attract into your life.
On the other hand, if you find that you have allowed the energy of unwillingness to flow within you, then you will find that your energy cannot help but attract what you desire and dream of.
