Are you the type of person that thinks that if you worry about something you are exerting some sort of control over it? That if you think about and analyze every possible worst case scenario that you are better equipped to deal with them if they actually happen?
I used to be one of these people. I picked up the habit in law school where they told us that if we could anticipate every move the opposing party and the judge was likely to make then we would be more likely to win the case. Although preparation might be a good idea in the courtroom setting, applying it to your life does not work.
In her book Presence, Amy Cuddy destroys the theory that worrying equals success. Her studies show that the more successful a person is, the less anxiety they experience.
Worrying = control = successful outcome is a house built upon the sand, a completely flawed premise. In fact, the opposite is true, the less you worry and the more you trust in the universe's ability to deliver successful outcomes, the more likely you are to experience them. So you can let that mental program go and start to experience the life you were meant to live, a life without anxiety.
