on Writing Forward:

The more you write, the better your writing becomes. That’s not an opinion; it’s a fact. Experience breeds expertise, so if you write a lot, you’ll become an expert writer.
Writing every day is the best way to acquire lots of experience.
Writers who come to the craft out of passion never have a problem with this. They write every day because they need to write every day. Writing is not a habit, an effort, or an obligation; it’s a necessity.
