"Don't get your hopes up!"
Were you warned of this as a child? What does this say? It says that life is bound to disappoint you. It says, don't aim high because you're not likely to get what you want. It says that we can't expect good things to happen to us.
As our thinking creates our reality, this kind of thinking dooms us to a mundane existence. It's time to change our stories. Why not focus the immense power of our hearts and minds on bringing to fruition the very best life has to offer? Allow yourself to hope and believe in all possibilities.
