In this post, Nicole J Leboeuf (

"I can only presume that such doomsayers are themselves struggling or even published writers who feel threatened by the army of would-be writers hurling themselves bodily from catapults at the great stone wall standing between would-be and did-become."
and:
"So fie upon doomsayers. You'll give up when you're dead. Until then, for as long as you love it, keep writing."
And I agree. :) If you want to write--and you love it--do it!
