I Ching readings here
The first hexagram means you don;t need to cast around outside yourself for answers - you have all the answers inside you from your own inner wisdom that you must allow to emerge in its own time. And yes, "it is not so terrible to not know something (for example on my job, i always fell anxious about it)." The second hexagram says that, if you remain constantly peaceful and calm, the answers will come, but being anxious and fearful will produce nothing but negativity and puzzles.
