Anxiety is defined as a possibility of a possibility. That something is possible and there is leap between its mere existence and possession by you.
Anxiety is identical to dizziness. When one looks down a great height, one's eyes become dizzy with the possibility of a fall. If that feeling is misunderstood and the person detaches himself from the past , he suffers from guilt. But when he understands the feeling, he cannot be deceived by that emotion and uses it to educate himself and go wherever he wants.
Comparing it with the process of creation, the possibility of destroying the status quo always exists in it, replacing the status quo with new things. If that is not done, then a feeling of guilt sinks in. However in order to create something new, a past has to be destroyed. In other words, Creativity, anxiety and guilt go side by side. What is required, according to Soren Kierkegaard, is to not let the guilt bring you down.
