Ray Bradbury said this quote
“ Not much to say except to warn you not to get too serious about all this, if you want to become a writer of fiction in the future. If you intend to become a critic, that is a Whale of another color…Playing around with symbols, even as a critic, can be a kind of kiddish parlor game. A little of it goes a long way. There are other things of greater value in any novel or story…humanity, character analysis, truth on other levels…Good symbolism should be as natural as breathing…and as unobtrusive. ”
