It is lazy blogging to suggest that there are two types of anything (though it has never stopped me before), but I do believe that writers can be roughly split into two groups.
Writers Who Write
The first group is writers who simply must write. These are writers to whom writing is second nature, it is like breathing. These writers will write no matter what. The simple act of placing words on a page, conjuring up worlds and passing ideas, is like a drug and they need their fix every day.
Writers Who Deliver
The second group is writers who write for a goal. These writers write because they are looking to produce an end product. For this group the final book, manuscript or essay is the payoff, not the actual process of writing. This group can goes days without writing, but will write every minute possible if the deadline for a project demands.
I fall into the second group – what about you?
