Do your homework on where to send your work. Sometimes you can send a piece out cold and get a deal, but that is the exception and not the rule. A cold submission means that you haven’t really researched the magazine or publisher and just sent your work to them, hoping for the best. This has worked for me, but for the one publisher who published it, there were many others who rejected it. There have been pieces that I wrote specifically for a certain magazine and those pieces were accepted immediately. And that is what you’re looking for - a perfect fit. You want the right piece of writing in the right magazine. You want a win-win situation for the work and publisher. I’m not saying that you sell-out and write only for a magazine. Write what is inside of you to write, but find the match for that work. If there isn’t really a match, then try to cold submissions, but don’t get discouraged when the rejection slips come in. It’s just part of the process.
