How accurate are Tarot Card Readings?

In life, there are certain things that are in our control and there are certain external factors that are not in our control. Tarot cards are very accurate in terms of providing guidance and direction, but may not be so accurate in predicting the future. It is believed that a huge part of our destiny is in our own hands so it is the decisions and choices that we make eventually get us to where we want to be in life.
Also, the accuracy of the cards may also be determined by a good Tarot Card reader.
