The key to bringing something into your experience that you desire is to achieve vibrational harmony with what you desire. And the easiest way for you to achieve vibrational harmony with it is to imagine having it, pretend that it is already in your experience, flow your thoughts towards the enjoyment of the experience, and as you practice those thoughts and begin to consistency offer that vibration, you will then be in the place of allowing that into your experience.
Now, by paying attention to the way you feel, you can easily know if you are giving your attention to your desire or if you are giving it to the absence of the desire. When your thoughts are a vibrational match to your desire, you feel good, your emotional range would be from contentment to expectation to eagerness to joy. But if you are giving your attention to the lack, or absence, of your desire, your emotions would range from feelings of pessimism to worry to discouragement to anger to insecurity to depression.
And so, as you become consciously aware of your emotions, you will always know how you are doing with the allowing part of your Creative Process, and you will never again misunderstand why things are turning out the way they are. Your emotions provide a wonderful guidance system or your and if you pay attention to them, you will be able to guide yourself to anything that you desire.
