I think you are absolutely correct. If you mentally prepare yourself for something…rehearse over and over in your head…you see yourself in a more confident way. Confidence can take you far. If you cannot see yourself doing a TED talk or running a company, chances are you never will. It is more than a wish. It is envisioning a place in the near future that you plan to be…and the more you do it, the odds get better that you will.
