An affirmation states that a goal is already happening. I'm not crazy about this because, often when we affirm something that is not yet real, the little voice in our head usually responds with This isn't true, this is BS...On the other hand, a declaration is not saying something is true, it's saying we have an intention of doing or being something. This is a position the little voice can buy, because we're not stating it's true right now, but again, it's an intention for us ion the future.
