Those little coincidences, chances, that happen in everyones lives, but that not everybody is aware of. I believe these things are not coincidences at all. On a more serious note, we have futurology, which is basically about predicting future trends (short-term, middle-term, long-term) on the basis of present preferences, or "hints". I think the same can be done in your everyday personal life, if you pay attention to these "messages".
The same Q.
