It is impossible to negatively define a thing.

You can say all day long what something isn't and still not have explained what it is.
When people say what they *don't* want, and what they *aren't* willing to do this is an indication that fear is a key driver in their process.
Everyone knows that when someone says, "I don't mean to pry..." or "I don't mean to be judgmental..." that the opposite is true.
When you hear yourself saying, "I don't..." recognize it and say what you do.

What do you want?
What are you going to do?
What do you want to be?

Simply stating things in a positive way - defining things positively - erases any doubt and seeds your creative subconscious with what to manifest.
