In a tarot reading, usually there is a tarot reader and a Querent (unless the tarot reader is reading for himself). The Querent will ask questions and then the tarot reader will pull some tarot cards for the Querent, or sometimes ask the Querent to pull some cards himself, and answer the questions based on the meanings of the cards.
How we think now will to a large extent determine our future, or destiny. Of course in life there are factors that are out of our control, we call them fate. Through the process of tarot reading, we are making our unconscious thoughts, conscious. If they are positive thoughts, it will be good sign of a brilliant future. Just work hard and go for it! If they are negative thoughts, we are now made aware of such. We can change the way we think, and choose our own destiny by walking a different path.
