“Keep writing” seems like some obvious advice for anyone with creative writing ambitions, no matter how large or small. There really isn’t much else to writing other than to do it, and continue until you can do it well. You can read fiction, read publishing advice books, read writing websites (like this one!), but at the end of the day, practice is the only way to hone your voice.
I throw the “others have said this much better, but it bears repeating” disclaimer about here in the post. I’m not pretending to have some significant insight, just the experiences of my undergraduate career that I think others could learn from.
First, comrades, we must discuss the idea that we are writing all the time. Many of you will no doubt protest: “But I set aside special time for my fiction/poetry/satire. How can you tell me I’m always writing it?”
