You can also work the other end. Like maybe the idea you pitched didn't really work out. But still, at $14/w (my average), if you just file a paragraph or two then you'll still make some prosciutto money.
my one tip for the “how can young writers make more money?” discourse is to note that editors will often pay a bonus if you go long. So like, my Gawker contract was $8/word, but I’d often file 2–3 times as many words as initially agreed upon, and they’d bump me up to $10/word
