You may think that you're "thinking positive" because you're scanning the near horizon for hopeful signs. That's a good start, but there is more to it than that, Sagittarius. You must also have true hope in your heart, and you have to actively deflect negative thoughts and fears when they occur to you. And most of all, you have to be consistent in refusing to entertain visions of what could go wrong. You may have great hope for the outcome of an endeavor that is now developing. Dedicate yourself to optimistic faith, and you will realize your dream.
