The book National Velvet by Enid Bagnold was probably responsible for more girls wanting to ride horses than any other book that comes to mind. The late Ms. Bagnold in her autobiography titled simply Enid Bagnold's Autobiography had something great to say about writing as a career.
Who wants to become a writer? And why? Because it's the answer to everything. To "Why am I here?" To uselessness. It's the streaming reason for living. To note, to pin down, to build up, to create, to be astonished at nothing, to cherish the oddities, to let nothing go down the drain, to make something, to make a great flower out of life, even if it's a cactus.
That's pretty much it in a nutshell.
