To write is to carve a new path through the terrain of the imagination, or to point out new features on a familiar route. To read is to travel through that terrain with the author as a guide- a guide one might not always agree with or trust, but who can at least be counted on to take one somewhere.
It is said that you can't write without a reader. The opposite holds true as well; you can't read without a writer. But if as a single, creative person you are one in the same, then, well.....problem solved! Great writing is born from that which we personally long to read.
