Paul Gallico said this quote
“ It is only when you open your veins and bleed onto the page a little that you establish contact with your reader. If you do not believe in the characters or the story you are doing at that moment with all your mind, strength, and will, if you don't feel joy and excitement while writing it, then you're wasting good white paper, even if it sells, because there are other ways in which a writer can bring in the rent money besides writing bad or phony stories. ”
