Do predictions come true?

Do predictions come true because they were destined to come true, or because people make them happen because it was predicted (like a self-fulfilling prophesy)?

I believe that there are many ways that predictions can come true. They come both ways, but it all depends on that person. Depending if that person is dedicated enough to make their own or even another persons prediction to come true. But it take a while it doesn't just happen over night, you have to and try and accomplish your goal or mission first for a prediction to come true.
