Whenever that voice in the back of your head starts to tell you all the reasons you cannot meet the current challenge add the voice that reminds you of what you have already achieved. It is not the first time that you have been faced with some difficult situation, and it is not being Pollyanna to put the issue in a personal historical framework. You have gone through other obstacles, and I would venture to say that most of them have been negotiated successfully. Instead of magnifying the challenge by merely focusing on how difficult it is conjure up all the times you solved similar or even greater challenges. Everyone has that little negative voice in their brain but it is wise to make room for the positive voice also.
