I believe in signs. But I do not believe they are sent from the space and beyond. Those signs are created by your own thoughts and beliefs. I mean, it can rain everyday right? But the day that you are getting married, or making a life changing choice it suddenly rain cats and dogs.
Those signs you create, may be unconscious at first, but if you really think about it, those signs are really a manifest content of what's latent. In lamest terms: you saying that because is raining you can't do something, might mean that you are not ready or not comfortable with doing something.
I suggest you to follow those signs, not because they are being send by the all-mighty-universe-know-it-all. But because what those signs really are, are your feelings. People, we actually, tend to lie to ourselves that something is right when it isn't. Listen to the signs, because those signs is you telling yourself what's right.
You are the universe (Wow that was deep ha ha).
