The Tarot is like water. If you get excited about an outcome and it changes, it’s not that shouldn’t trust your intuition. It’s that life is like water, especially when other people are involved. The Tarot is a guide and a good reader does their best to be open to the message of the moment.
But YOU are the master of your life and things shift and flow all of the time in daily life. Believe that the Universe / Higher Self have your best interests at heart, even if you feel disappointed in what you thought was the right way at the time. Wait it out, be like water instead of rock — and see what flows in next.
