There not really anything I can think of that I would want to believe in again, as we grow up our beliefs are sometimes cut off but it's part of reality and growing up. Of course we still believe in things and we should continue to believe in things like goals, people, and religion. On the contrary some believes, such as creatures, "Santa", and things that aren't real. It is good to have a sense of imagination, but as we grow we must realize that we have to grow up and face reality.
