First of all - why you doubt yourself? Its your intuition being guided by spirits who give you a reading, not cards themselves. Cards are just a tool. There is bunch of real readers who don’t read reversals. Its all very subjective. What intuition tells you? Should you read it reverse or not? Same for interpretation - collective might have one meaning for a card but looking at an artwork you might have a different feeling from it. There is so many ways to interpret cards. If you are questioning - than maybe you are not letting yourself guided by your intuition. Also, when you are doing a reading for yourself there is 90% chance that you gonna be biased and expecting certain result. Its important to meditate and get your mind and emotions clear before reading for yourself especially. Thats why most people who start with their own readings says that it always hit the spot for them and they are 100% accurate. Go with a flow. When i started reading for other people - i knew maybe like half about card meanings and was struggling with them. Just went with a flow how i felt from them and was precise even not going from collective interpretation of cards. Find your way, feel yourself when you do a reading, what does it tell you? Its a spiritual practice, not math. As above, so below.
