What part does personality play in writing?

There are so many facets to the question I’m posing myself that I can’t even begin to pretend that I could answer them all, or even that I’d want to, but at the moment I can’t stop thinking of the ways your personality affects your career rather than your writing itself.

I know a lot of writers and artists who have massive personalities – some of these I like better than others but you can’t deny that a lot of them grab attention. I’m not the shyest person in the world or anything, but I certainly don’t have one of those larger than life personalities and I can’t help wondering if that’s going to end up being to my detriment when it comes to writing.

You need to shout your corner at some point and without at least a little self promotion you can be pretty assured no one is ever going to get around to reading your stuff, but it doesn’t come easy for plenty of people. I just hope those aren’t the same people that don’t see their work in print in the end! I guess that’s what makes an agent vital for many writers, thing is you still have to sell yourself to an agent at the outset. Maybe I need lessons in creating an alter ego, one with plenty of moxy!
