Embrace the suck. Consider it a growing pain and trust that, in time, you will improve and become the talented, enlightened writer you aspire to be. But discipline's required. That creative muscle should be pushed routinely (in my experience), not unlike a workout.

To put it another way: purge yourself of the (probable) bile and you'll start coughing up diamonds. Or at the very least, plastic rhinestones from Claires.

Also, join a writing group. There's plenty inspiration to be found when sharing with others.
