Self Fulfilling Prophecy
A Self Fulfilling Prophecy is a prediction that causes itself to come true due to the simple fact that the prediction was made. This happens because our beliefs influence our actions.
For example, if a woman thinks that her husband will leave her for another woman, she will act in ways that will directly or indirectly cause her belief to come true. She might get jealous easily and make a fuss about him being friends with other women. She might pick fights whenever she suspects that he is cheating on her, or she might go through his personal things to look for evidence of cheating. Eventually, her actions will put a strain on their marriage, and her husband just might leave her, causing her prediction to come true.
