As a tarot learner I am trying to keep this in mind. It really can be helpful.

The card interpretations can be a little intimidating at times. I try to balance the meaning of cards with both positive and negative associations. The downside is this, while the upside is this.

On rare occasions, you sometimes get a spread that is all negative, and there is no other way to interpret the cards or put a positive spin on them. It's just a bad situation. These instances are usually rare though.

It's also important to look at the surrounding cards and how they interact with the negative card or cards.

When dealing with reversals, I tend to use the upright meaning just to a lesser degree. Sometimes if most of the cards are upright, I may even ignore the reversal, unless the reversed card seems to be directly correlated to the question. That's just how I was taught though.
