|This is a neat idea for a story. I think it would be better if it used more concrete details, though, and if the ending had a stronger ironic resonance.
I'm calling it an idea for a story because it only sketches in the abstract form of the protagonist's desire and her problem. This is not a matter of "telling" vs. "showing" -- it would be too tedious to "show" Karie's desire and her struggle. But the related details could be more vivid.
She wants "fame" -- but what does "fame" mean to her? To have her name plastered online and in print? To have her picture everywhere? Her opinion sought? A colorful vignette imagining the glorious experience of being famous -- the popping flashes and the gasping crowd as it surges at the scarlet carpet while the Botoxed reporters thrust microphones at Karie's face, say -- would tell us what kind of fame she wants, and why *this* contest will get it for her.
Similarly, it would be nice to get vivid details of what it's like to be distracted and unimaginative while trying to be creative -- if you're anything like me, you know what *that* is like. The hot headache caused by an empty brain; the wrong words scraping against each other and refusing to spark ideas. Also, the joys of procrastination: the blessed ding of a text or email alert; the obsessive emptying and loading of the dishwasher; the plunging of the hand into a box of Pop-Tarts, and the snap decision to go to the grocery store NOW because there are only five left. I think details like these would be nicer than "Nothing done".
Also, and I hate to say it, but: It's kind of a cheat to not reveal Karie's great idea at the end, unless you want to turn the secrecy itself into a joke about the way writers can fool themselves -- she announces she's got the idea, maybe, and promises herself she'll tackle it after school, but once she realizes she's lost she discovers she's forgotten that winning idea. (I've lost so many ideas because I've delayed writing them down.)
The ending: It seems like there is supposed to be some irony there, but I'm not sure what it is, because the horror of delaying so long that her sister gets the call is not itself ironic. Perhaps her sister kept distracting Karie and that's one reason she couldn't come up with an idea? Perhaps her sister has ideas -- multitudes of them -- but doesn't want to be famous?
Finally, even in its current form, I think the existence of the sister should be established earlier so that it doesn't come out of nowhere at the end. Also, unless there is some undercurrent I'm missing, I think the sister's name should not be so similar to Karie's. I had to go back to reread the beginning and ending to confirm that these were different people.
I mean all of these suggestions as dabs of plaster onto an already strong skeleton.
