Failure isn't a matter of aiming at Cosmopolitan and missing. Good writing evolves over time. The reality of writing is that when you start, you think you're pretty good. After a year, if you've been writing steadily, you're likely to look back on those first efforts and wonder what on earth you saw in them. After you've been writing for five years, you may look at those first-year masterpieces and wonder why you didn't burn them on the spot.
Writing is a somewhat schizophrenic process.
Both statements are true. Tomorrow, quite probably, you'll do better. But only if you don't stop writing today. Get Over It. Get over it.
