I can't make sense of the i ching

I'm discovering tarot reading, and since i found it to be a valuable tool i started experimenting with the i ching too, but i'm having trouble understanding and interpreting the meaning of the hexagrams. Sometimes half the reading makes sense but the other half feels completely unrelated, expecially if i try to see the first hex as the situation and the second as the probable outcome. Sometimes it makes more sense but it still feels not so much informative on how to proceed, i find that with tarot i have more useful information and meaning feels a lot more intuitive and less of a stretch. I feel like i don't have the right framework in which to interpret the symbols. I use the Wilhelm book. Do you have any advice on how to make sense of it? Is it common in the beginning or is it just not for me?
