You will only allow within the boundaries of your beliefs
Unless you are deliberately suppressing your wanting because you have wanted and not received for such a long time that you have given up on your wanting, then being ineffective at the wanting part of the equation is not usually what is keeping you from deliberate creation.
It is that you do not allow because you do not believe.
What you believe regarding anything that you want is extremely important - for you will only allow within the boundaries of your beliefs.
And so, in many cases your beliefs must be altered to harmonize with your intentions.
When you understand that your beliefs, also, are creations set into motion by you because of previous experience, then you realize that your beliefs are not unchangeable, but, instead, they are pliable and moldable.
Your alter your beliefs by applying new or additional thoughts to those beliefs until you have molded them into that which you now prefer.
