I don't remember how I found this article, but I thought it sounded like a great idea! Write a story a week to improve your craft. The website The Write Practice gives you a daily plan on how to accomplish this feat.
In a nutshell:
Monday - Settle on your story idea.
Tuesday - Write your opening act.
Wednesday - Write the climax.
Thursday - Resolve the plot.
Friday - Revise your story.
There are much more detailed instructions at their site, so go check it out and let me know how you did. If I attempt this massive undertaking I will post my stories here and on Wattpad.
