The advice was this: if the card you draw doesn't seem to fit you or your situation, start writing about that. Write about how it doesn't fit you at all, about how it was a mistake to draw that card. Write about why you can't possibly learn from it. By the end of your writing, you'll see why it was the card you were meant to draw all along.
When we perform divination for ourselves, we're all at the risk of seeing what we want to see. We draw another card "just to be sure", or interpret things in the broadest possible terms. It's one of the reasons even Tarot readers get readings from others: sometimes we just can't be objective about our own situation.
But when our purpose in reading is to spiritually delve, to see what we can dig up within ourselves, it's important to understand that there really are no accidents. There are many, many paths to the heart. Sometimes, in discovering what doesn't feel right, you can make room for what does. Sometimes in asking the wrong question, you stumble how it leads to the right one.
It's an excellent lesson for life as well: don't wait for it to be the "right" moment. Keep going, do the work, and the road will lead you to the answers you're meant to find.
