Clearly, our world has room for both types of writers. Writing isn't inherently noble, painful, or glamorous. Others have lives that aren't especially noble, painful, or glamorous at all. Still, certain stereotypes about writers and writing manage to persist. Like all stereotypes, they are made up of a little bit of truth and a lot of exaggeration and over-generalizing.
Writing is glamorous.
As for the act of writing itself, you'll soon discover for yourself, if you haven't already, that it's not glamorous in any way. Writing is an act and a process, not a definition of who you are. When people hear that you're a writer, some of them will jump to all sorts of conclusions about you. Do these people a favor. When one of them begins treating you like a stereotype instead of a human being, tell them a few things about yourself that are decidedly unstereotypical.
