There are hidden messages everywhere. Pay attention to the lyrics in the songs you enjoy listening to. Go to the movies with an open mind.

One of my favorite tricks my husband taught me is to pick up a book and open it to any page. It is amazing how you will generally open to a page that will help you find the answers you are seeking. I have even done this with my own journal from time to time.
Be aware of your surroundings and you environment. What we project to the universe is projected right back at us.
