I sometimes find tremendous insight in a piece of literature that is analogous to real life difficulties. Provided that, that piece of writing, also offers some sort of a solution to the "problem".
Those problems I'm referring to are for example confidence, psyche (esp. C.G.Jung), getting over traumas etc.
Obviously, my formentioned cases are not extensive and everyone finds something else that they struggle with where a piece of literature might help.
2. Thank you for your insights. If your answer to question 1. is no, I'd like to know what kind of analogies you think are valuable and why?
