So I have this question in my head for a long time now , people often say you must say the big dreams out loud in the open for the universe to hear it and grant it to you but some people say that u must do things in private like if u want to achieve something big u must stay quiet and do the grind in silence so that nobody can take that away from you or something like that, I just wanna know which one is true ? Or like either of them are just as stupid and things only happen when they are supposed to happen..
