Impatience equals resistance which leads to not manifesting. Impatience causes tension in the mind and the body, causing negativity and shielding us from positive thoughts!
Patience leads to instant manifestation because it doesn’t invite resistance or a lack of satisfaction with one’s current reality. With that, patience also leads to letting go.
If you are patient and grateful for your life as it is, you will be alright living without your desire which will allow you to let go and manifest.
