That is about four questions. Three card readings on good on focusing, narrowing in on ONE area.
What I got from the reading and what your response seems to underline and confirm is that you may be reading a lot, but you are not understanding what you are reading. You say you are not satisfied.
So yes, practice is important, but understanding, finding a method that works for you, perhaps finding out what resonates more for you (is it tarot, Lenormand, oracles?), because in the end....it is about you and the cards.
I would suggest trying to journal for a bit. Take ONE deck, whether tarot, Lenormand, oracle, and just sit with the deck and just write your thoughts for each card.
You may be trying TOO hard, running from deck to deck, tarot, Lenormand, oracle, rather than just working with one. What I got most from your reading is you must settle your mind, it is you, not the cards, that does the reading. You must make peace within yourself and that will help you make peace and be more satisfied with your readings. The cards are just a tool, it is all about you and what you see in them.
