The important thing about doing a reading is to use your intuition. Those gut feelings, or those hints and nudges that you feel. Have you ever felt like doing something, yet you thought you had no reason to, only to realize you should have done it! Well that was your intuition trying to hint something at you! It's quite natural and happens to everyone.
So becoming a good reader comprises of knowing your card meanings, yet also knowing to lead with your intuition. You don't just stick to the card meanings you know stubbornly, refusing to learn new ways! The more you practice, the more you will see that there are various ways to read each individual card. Each time a card shows up, it'll have a slightly different meaning, tailored to the question at hand!
The question is a very important component to the reading. More specific questions lead to more specific answers, where as vague questions will lead to vague answers! So if the topic is about love, ask about a specific incident revolving around it. Ask "How do I..." or "What do I..." instead of "Will I..." or "What if..." questions. It is also advised not to ask "yes" or "no" questions, simply because they're difficult to read for.
It's also important to be able to look at the overall spread and be able to
combine card meanings with one another to get the overall
interpretation. It might be a difficult feat at first, yet it becomes
more natural once you understand more about each card. But to start off, just learn the card meanings, and then try this at a later date.
Also you don't have to keep repeating the question in your mind. Just remember the question, and conduit the reading. Some readers like to keep a journal to jot down their questions and answers, just to keep track of things.
Ask questions that help you grow and learn as a human being! Ask for advice if you're feeling stuck. See where it takes you.
But you should know that just because you read something that looks bad, doesn't mean that you doomed yourself to it! There is always a lesson you learn through life's trials. That is why you are on a path, to learn about important and valuable lessons. Sometimes when you see the cards laid out before you, it feels like it's a diagram that helps you look at the problem and find solutions. You could then ask the point of it, the lesson of it, or advice about it. You could also ask what would comfort you in this time. They're all valid questions.
Remember to pace yourself while learning, and when you get a little bored, challenge yourself! Yet if you're already having trouble learning, don't add more challenges to the mix! Learn what you're comfortable with, and remember to keep practicing!
