You want advice on submitting your work?
I'll give you advice.
The trouble is I've given this advice before. Many times. I, or one of my team leaders, give this same advice almost daily. We reject stories because of it. We waste our time and the time of aspiring authors because of it.
Here it is.
Because I feel like yelling it...
READ MARKET GUIDELINES!!!
(Three exclamation marks, even.)
If you haven't visited a market in awhile--say 6 months or so--review the guidelines.
If you're submitting a story or novel for the very first time, read the guidelines.
If you think you're a big hotshot author who will obviously have his/her story land right on the top of the slush pile because of your impressive list of publications, despite the fact that you choose to ignore the guidelines, think again.
If you think guidelines aren't important, think again.
If you think it's fine for you to waste someone else's time--particularly someone who might pay you for that time--think again.
And do more than just read the guidelines.
Read them CAREFULLY.
Then HEED them!
Read n' heed. Read n' heed. It's really not that complicated.
