In the movie the Butterfly Effect, the main character tries to go back into time to rectify an unfortunate situation. He keeps trying to fix the problem and goes back in time multiple times. But every time he goes to fix the problem, he never seems to turn the problem around. At the end he discovers that the root cause revolved around a certain relationship with a person that he met as a child. So, he goes back in time one final time and makes sure that he never meets this person in the first place.
The moral in this story is that sometimes in life, we meet a certain person. You know that deep in your heart that if you continue on the relationship with this person it will eventually lead you to a path that is not to your liking. Unfortunately, we cannot go in time like the character in the Butterfly Effect. The only thing we can do is recognize a situation when it does come up and listen to your instinct. Your instinct will tell you whet it is best to continue the relationship or to sever it at the beginning before a potentially detrimental situation can come up.
As an individual, you meet new people all the time. It could be a new client, it could be a candidate, it could be a new potential business associate. The next time you meet a new individual at some point, your instinct will tell you whether this is the right person or not. If your instinct tells you it's not, then you may have to do the right thing and end the relationship.
