I've had the same thing happen to me in the past. My explanation is that tarot often reflects current energies, it doesn't mean that those energies are going to take a concrete form, if you see what I mean..
I didn't make it through the entire thread yet, but what Nikita says is pretty much how I feel. When drawing my own cards, I've experimented with my own frame of mind at the time. While I do like to focus on my "issue/question" I try very hard not to wish/hope for a certain outcome while I'm touching the cards (shuffling or drawing). If I approach it from kind of a mindful spectator type of angle, I feel I can get more accurate.
Also of note is the deck choice. I have like 50 different decks and most are just ones that I liked the look of, but there's only 2 decks that I actually use (a Morgan Greer deck that was handed down to me by my Uncle, and a Sacred Rose deck). If I use other decks that I don't really have a "connection" to, I don't get very accurate results either.
