Dealing with criticism--both self and from others--and editing (read re-writting) are essential to go from being an amatuer to a pro whenever the writting word is involved.
My experience is of the very dry non-fiction sort (reports, academic stuff), and if you can't take criticism, and rework what you have done, you might as well stop wasting your time...I can only imagine that in the case of fiction writting (that is actually published) it is only more so, or at least should be.
Then there is game design. You can find good writting in games: flavourfull text that bring the game alive and conscise descriptions that make mechanics clear. And then there is the other. But I honestly believe that with all the competition out there, people are not going to spend a lot of time on products that are poorly written (though I guess there are exceptions)
