For the most part, this theory refers to personal/inner thoughts and feelings fulfilling themselves in an outward manner...but I've recently noticed that this phenomenon can be more powerful if your self-related thoughts are made public. If you write something down, post something to the internet or tell a friend, I think your chances of self-fulfilling are much higher. Once you've consciously recognized that thought, or even shared it with others, your subconscious desire to fulfill it skyrockets.
I've noticed thi
s even in myself. There is a section on Facebook located right underneath your profile picture that asks you to, very simply, "write something about yourself". This box is big enough only to host a sentence or two, so I felt that if I was going to write only one sentence about myself, it better be something good. I noticed that some of my friends had written things about their families, jobs, hobbies or quotes from famous people. So I did some thinking and web browsing to find something clever to "write about myself". Finally I decided on a quote I found that says, "I say luck is when an opportunity comes along, and you're prepared for it."I've never said that quote aloud and I don't know if anyone has ever even read it in on my Facebook page...but ever since I put that "personal thought" about myself in a public place, I've noticed that more of my actions lead me towards fulfilling it. Because I chose to publicly associate that quote with my personal characteristics, I think that the self-fulfilling prophecy kicked into turbo-mode because if I didn't self-fulfill, I wouldn't be the only person to realize my "failure".
There you have it; my belief about the self-fulfilling prophecy: If you publicly announce something about yourself, your rate of self-fulfilling that sentiment is higher than if you were to keep it to yourself. Take it or leave it.
