Amy Cuddy is a social psychologist on the faculty of the Harvard Business School. This talk "could" change your life, or then again... maybe not. I'm not positive I would bet my life on it, but it does seem to have some merit. Take a look at it, try it out, and see if it works for you.

"Why you should listen
Amy Cuddy wasn’t supposed to become a successful scientist. In fact, she wasn’t even supposed to finish her undergraduate degree. Early in her college career, Cuddy suffered a severe head injury in a car accident, and doctors said she would struggle to fully regain her mental capacity and finish her undergraduate degree.
