The big questions are:
1) How much of your creative output (product of your brain) comes from reading (be it books, blogs, whatever) and writing (when you write you read at the same time)?
2) How much of creative output (product of you brain) falls into oblivion, because you only feel what you want to write, dream about what you want to write, you think what you want to write, you fight with yourself about what you want to write (but you never write it), because you're either not drunken/high/religious/not in good mood/not educated enough to write about it. Or simply feel ashamed or feel that what you write is inferior in comparison with what others wrote in the past.
