Cassandra was the daughter of the King of Troy, Priam. She was so beautiful that the god Apollo gave her the gift of prophecy. However, Apollo could not keep his hands to himself and wanted more from Cassandra. She rejected his romantic advances, so he also cursed her that no one would believe her prophecies.
Cassandra was left with the ability to foretell the future, but unable to change it because no one would believe her; this included the imminent destruction of Troy by the Greeks.
While I don’t think any psychic would claim to be 100% accurate, skilled one’s can be very good, averaging between 80-90% accuracy. Despite this prove track record, psychics are often ignored, sometimes even by paying clients.
It is truly heartbreaking to watch someone, whether a client, family or friend, walk right into a ditch that we told them about. Family is the worst, since they know the psychic intimately, warts and all! They can easily discount the warnings.
For the developing psychics out there: take courage. Detach. Daily meditation helps. Your warnings will often be ignored. You must be willing to let go and walk away. It is the only way to preserve your sanity.
