Stop Prioritizing External Confirmation
So, I assume many people in the LOA community are familiar with the following mantra by Neville Goddard.
Consciousness is the only reality.
Now, consciousness in the context of NG's words can be substituted with your wonderful human imagination, the 4D, God, our inner self, etc. They are all the same thing - our own means of experiencing and appropriating our desires.
With this knowledge, you should know that whatever is done within is infinitely more important than whatever the outer world shows. That includes whether or not you are seeing the 'results' of your manifestation - if you have it in your imagination, you have it period.
The world is a mirror, a response. There is always change in movement, because you are always changing and moving within.
I know it's easy to get caught up in the physical world and accept that as reality. It's easy to try to make external efforts to chase the things you want - but in reality, it is all done in vain if there is no change within. The 3D is impersonal, it is not trying to sabotage you, it will only reflect what you feel inside.
Therefore, you must learn to use your imagination as proof. You want your desired face? You just imagined looking in the mirror and viewing it! Money? Fame? You saw it within! That is proof enough. Your manifestation will bear its fruits, and it will not be late.
Keep the faith, and be confident in yourself. You will not fail. It simply does not exist.
