I believe that every person put out energies that influence the world around them. Not straight up bend it to one's will, but those thoughts and the energy they produce will sometimes "nudge" things. It's really not much different than a person of a Judaeo-Christain faith praying to God, or a Wiccan/Pagan casting a spell in the name of their Lord and Lady, or a Buddhist meditating on some kind of symbolism, etc, etc, you get the idea. Those expenditures of energy, combined with working toward your goals helps to fulfill them. More on point, those energies are very much determined by your thoughts, emotions, point of view, all of that. Your thoughts very much so help to determine your reality, both in a metaphysical and psychological sense.
I hope I explained this one well enough, I'm writing at 2:30 in the morning after playing a lot of Halo Online. My brain is cooked XD
