What kind of reading were you trying to do? I would assume Tarot, but since there are many other types of divination, I can't be sure.
It takes practice to do any of these kinds of readings: practice, study, and time. Some people have a knack for it, so it comes easier, and other people have a very hard time with it. It varies from person to person. There really aren't "easy" readings, per say. They all take practice to get good at, although, you may find that some come easier to you than others. Experiement a little bit.
