From The Secret - Speak only the words of what you want.

One of the things that people often do when they have an illness is talk about it all the time. That's because they're thinking about it all the time, so they're just verbalizing their thoughts. If you are feeling a little unwell, don't talk about it - unless you want more of it. Know that your thought was responsible and repeat as often as you can, "I feel wonderful. I feel so good," and really feel it. If you are not feeling great and somebody asks you how you are feeling, just be grateful that that person has reminded you to think thoughts of feeling well. Speak only the words of what you want.
