That’s what they should warn journalism majors before they start their program.
Be prepared to get your world rocked, because you will write something that you think is really good and then your editor will rip it to shreds.
I’m still getting used to having my work torn apart by editors, and I’m a graduating journalism senior. Such fun!
I suppose getting harsh reviews is supposed to help you do better and build up your work as well as strengthen your skin against criticism, but sometimes I’m a big softy.
I just wrote a blog post for my internship, and I thought it was pretty good. It was about new bills on the floor of the House of Representatives that seek to cut off funding for family planning and reproductive health. I sent my blog to my supervisor, who proceeded to strikethrough nearly everything I wrote. Case in point: 
Talk about rocking my world. She told me my writing was still good, and it laid a framework for what she edited into the new blog post. But still, less than 10 percent of what I originally wrote was intact! I survived an editorial run-in.
It just goes to show you that no matter what sort of confidence you may have about a piece, it is still subject to the editor’s appeal. Just a reminder that I shouldn’t get overconfident in my writing, as well as I should prepare myself more for constructive criticism.
Real life 101 note: you may think what you wrote as a journalist is the cat’s meow, but just remember, you’re writing for an audience, and if your editor doesn’t like what you wrote – don’t take it personal when they completely scrap your work. It’s just the life as a journalist after all.
