The foundational truth of hypnosis is that our thoughts define our perceptions and behavior. By bringing a determined, "can do" attitude to the process, you are already well on your way to achieving the change you want.  

Positivity is a proactive. If, for example, you are using hypnosis to change a habit, your thinking shouldn't be "I hope this works," but rather "I'm making this happen!"

Choose success and expect to be successful!
