We all like to think that good writing will always get published. Sadly, this is not always the case. But things run in cycles and the publishing business is no exception. Magazines are a great place to break in. Learn the basics of marketing.
Some magazines buy all rights.
That means you can never sell the story again unless you get the rights back. Some magazines pay on publication. That means you won't be paid until your story appears in print. This could take a year or more. A good idea.
