I personally find that once I talk about an intention in public people around begin to mirror certain aspects of my personal beliefs and thoughts about that intention. This phenomenum increases in intensity the closer these people are to me, but it seems basically any stranger can serve as a mirror like this for part of the time.
And sometimes it's really obvious. Like once I talked about a subject incredibly important to me on a soul basis on a forum, and one of the two people talking to me, who was taking a critical, cautious and rational approach was called cynomar and the other who took an approach of belief and trust was called neverdoubt, and I spent weeks in a sometimes rather heated conversation between the three of us, before it dawned on me that I was sort of shadowboxing with my own soul, cause I was actually torn in half over this subject on an inner level and these two people were only kind enough to mirror this schism for me so I could come to terms with it.
So my advice would probably be to only voice your intent to the public if you are prepared to face human mirrors head on. I imagine it like Atreju in the Neverending Story, who to reach his goal had to pass through a mirror that showed him his true self.
