Change the word how to the word YES
In other words instead of saying how can I do this?
Say YES I CAN DO THIS!
This is very good. The Universe responds to what we think and feel and also what we believe, and takes our thoughts literally. So if we are thinking HOW, then there could well be a hint of doubt and that will attract obstacles. But if we are thinking YES, then the Universe says " right then, they believe that they can and that they actually ARE manifesting such and such a thing, so I shall give them what they believe. " Or as Louise Hay says in her book Heart Thoughts: I AM BEING RESPONDED TO BY A YES UNIVERSE.
Reality tips the scale when 51% of our thoughts are on the possibility of something rather than the impossibility of it, and potential obstacles. We may not know how it will happen ourselves, but the Universe does, and it responds to our thoughts - to our belief.
